 	  Move HSI48 enable from stm32_usbdev.c to stm32xx_rcc.c  From Mateusz
 	  Szafoni (2019-05-17).
 
-8.1 2019-xx-xx Gregory Nutt <gnutt@nuttx.org>
+7.31 2019-07-21 Gregory Nutt <gnutt@nuttx.org>
+
+	* drivers/net/telnet.c:  Handle ctrl events (SIGINT, SIGSTP).  From
+	  Valmantas Paliksa (2019-05-21).
+	* arch/arm/src/stm32/Kconfig:  Correct some typos in conditional logic.
+	  From Maximilian Kriegleder (2019-05-21).
+	* configs/stm32l476vg-disco and configs/stm32l4r9ai-disco:  Fix an error in
+	  defconfig files because a line in the rcS file was longer than the
+	  configured NSH command line.  From Juha Niskanen (2019-05-21).
+	* arch/arm/src/stm32l4: Make STM32L4 CRS synchronization source board
+	  configurable.
+	  configs/nucleo-l432kc:  Add new configuration settings to board.h
+	  configs/nucleo-l452re: ditto
+	  configs/nucleo-l496zg: ditto
+	  configs/stm32l476vg-disco: ditto  From Juha Niskanen (2019-05-21).
+	* configs/lpcxpresso-lpc54628:  Add another Twm4Nx configuration for
+	  working out the new CONTEMPORARY theme.  From Gregory Nutt (2019-05-21).
+	* Removed all references to CONFIG_DISABLE_POLL.  The standard POSIX poll()
+	  can not longer be disabled.  From Gregory Nutt (2019-05-21).
+	* Documentation/: Applies a stylesheet to static HTML files. I've also
+	  tried to put the TOC of each document to the side, where it made sense
+	  (in some documents the TOC was actually inside a section so it wasn't
+	  possible). In some cases the TOC is built with a table, in others with a
+	  <ul> element, so I had to accommodate for this. I also didn't go into
+	  collapsing, although this could really help for some long TOCs.  From
+	  Matias N (2019-05-21).
+	* configs: Change CONFIG_NSH_MACADDR to CONFIG_NETINIT_MACADDR  From
+	  Masayuki Ishikawa (2019-05-22).
+	* drivers/net/telnet.c:  I/O thread now offloads reading from socket from
+	  client thread to the I/O thread.  From Valmantas Palikša (2019-05-22).
+	* arch/mips/src/mips32/up_vfork.c:  Fix a copy-paste error.  On vfork, the
+	  GP register was being set to the new SP value vs. the context GP value.
+	  NOTED in Bitbucket issue 155.  From Gregory Nutt (2019-05-22).
+	* graphics/nxbe/nxbe_raise.c:  Fix a critical list handling bug in the
+	  graphics system.  When a lower-level window was raised while a model
+	  window was in place, then list corruption could occur.  From Gregory Nutt
+	  (2019-05-23).
+	* Rename all arch/<famil>/src/<chip>/chip to
+	  arch/<family>/src/<chip>/hardware.  This eliminates a name collision that
+	  is usually harmless but does cause problems at the time.  The problem is
+	  becauase the include path includes '.' and 'chip/.', therefore and
+	  inclusion like '#include <chip/mcu_header.h' can be ambiguous of a filel
+	  named mcu_header.h exists in bothe at both arch/<famil>/src/<chip>/chip
+	  and at arch/<famil>/src/chip/chip  From Gregory Nutt (2019-05-24).
+	* arch/mips/src:  Previous commit used CP0 register definitions that were
+	  not defined in the cp0.h header file.  Probably these were from the
+	  Microchip hacked up GCC toolchain but are not generally available.  Fix:
+	  Add definitions to NuttX cp0.h header file.  From Gregory Nutt
+	  (2019-05-25).
+	* mm/iob:  Eliminate some warnings about testing the value of an undefined
+	  pre-processor variable.  From Gregory Nutt (2019-05-25).
+	* STM32F7 DTCM add procfs register  From Daniel Agar (2019-05-25).
+	* fs/procfs/fs_procfs.c:   procfs_initialize() is used only within
+	  fs/procfs/fs_procfs.c and, hence, should be marked 'static'.  From
+	  Gregory Nutt (2019-05-25).
+	* configs/lpcxpresso-lpc54628:  Modify the TWM configurations to properly
+	  inject keyboard data.  This way, in the case of multiple NxTERMs, only
+	  the NxTerm at the top of the heiararchy gets the keyboard input.
+	  Otherwise, it is not possible to use multiple NxTerms with each the
+	  keyboard input going to a different NxTerm window.  From Gregory Nutt
+	  (2019-05-26).
+	* arch/arm/src/stm32f0:  Initial support for STM32G0.  From raiden00pl
+	  (2019-05-27).
+	  configs/: initial support for nucleo-g071rb.  From raiden00pl (2019-05-27).
+	* Here's a patch to split the STM32 FMC/FSMC functionality (FSMC = flexible
+	  static memory controller, FMC = flexible memory controller = FSMC + sdram
+	  support).  This commit makes FMC it's own thing rather than piggy backing
+	  on the FSMC code.  The peripherals have a few utility functions and this
+	  commits lets you have a common function in the arch/arm/src/stm32 rather
+	  than having duplicate functions in the board code.  From Jason Harris
+	  (2019-05-27).
+	* Rename STM32F0L0 to STM32F0L0G0 since it now also supports the STM32G0
+	  thanks to Mateusz Szafoni's contribution  From Gregory Nutt (2019-05-27).
+	* arch/arm/src/stm32/stm32_fsmc.h: Fix the include file guarding name in
+	  stm32/stm32_fsmc.h.  From Jason Harris (2019-05-27).
+	* Improvements for STM32 PWM
+	  arch/arm/src/stm32/stm32_pwm: add support for all PWM modes
+	  arch/arm/src/stm32/stm32_pwm: add interface to change PWM mode
+	  arch/arm/src/stm32/stm32_pwm: refactor pwm_mode_configure()
+	  arch/arm/src/stm32/stm32_pwm: STM32_PWM_CHANx corresponds to the timer
+	  channel and STM32_PWM_OUTx corresponds to the timer channel output
+	  arch/arm/src/stm32/stm32_pwm: add CHAN5 and CHAN6 to PWM_TIMx_NCHANNELS
+	  arch/arm/src/stm32/stm32_pwm: calculate the PWM_TIMx_NCHANNELS if
+	  CONFIG_STM32_PWM_MULTICHAN is selected  From raiden00pl (2019-05-28).
+	* arch/arm/src/stm32l4/stm32l4xrxx_rcc.c:  Use Range 1 Boost mode if SYSCLK
+	  is higher than 80 MHz  From Juha Niskanen (2019-05-28).
+	* arch/arm/src/stm32l4/stm32l4_i2c.c:  Add support for 16 and 120 MHz
+	  timings, board can use HSI16 clock for I2C  From Juha Niskanen
+	  (2019-05-28).
+	* configs/stm32l4r9ai-disco:  Add ksh config, some updates for I2C, SPI and
+	  DFSDM support.  From Juha Niskanen (2019-05-28).
+	* This commit implements RS485 RX/TX switching and RTS/CTS flow control for
+	  the IMXRT family.  It has been tested on 1020 but I don't see any reason
+	  for issues on any other family member.  From Dave Marples (2019-05-30).
+	* Make sure sections are aligned to 32-bits in all LD linker scripts.  This
+	  fixes and issues noted specifically for the SAMD21 by Bernd Walter, but
+	  should be applicable to all other LD scripts as well.
+	  configs/:  Add . = ALIGN(4); before every .data section
+	  configs/:  Add . = ALIGN(4); before every ARM.extab section
+	  configs/:  Add . = ALIGN(4); before every definition of __exidx_start
+	  configs/:  Add . = ALIGN(4); before every .init_section.
+	  configs/:  Convert TABs to spaces in all ld linker scripts.  This just
+	  makes things easier to modify with scripts because the files are more
+	  consistent.  From Gregory Nutt (2019-05-30).
+	* arch/arm/src/stm32l4/stm32l4_hsi48.c:  Enable CRS_CR_CEN with
+	  CRS_CR_AUTOTRIMEN  From Jussi Kivilinna (2019-05-29).
+	* arch/arm/src/stm32l4/stm32l4_pwr.c:  Enable PWR peripheral for setting
+	  USV  From Jussi Kivilinna (2019-05-29).
+	* arch/arm/src/stm32l4/: Fix USB device PMA accesses.  USB PMA accesses are
+	  done as 16-bit words on STM32L4 instead of 32-bit words on STM32L1.  From
+	  Jussi Kivilinna (2019-05-29).
+	* net/tcp/tcp_send_buffered.c: Fix deadlock in iob_copyin when iob buffers
+	  are exhausted and network lock is taken.  From Valmantas Paliksa
+	  (2019-05-29).
+	* arch/arm/src/stm32/Kconfig:  Add MEDIUM_DENSITY selection.  From Dave
+	  Marples (2019-05-31).
+	* arch/arm/src/stm32/stm32_adc.c: The attached patch fixes a compilation
+	  error when verbose analog debugging is enabled for the stm32 adc: not all
+	  stm32s have an SQR4 register.  From rajan gill (2019-05-31).
+	* configs/lpcxpresso-lpc54628:  Enable DATE command in twm4nx1 and twm4nx2
+	  configurations.  From Gregory Nutt (2019-06-01).
+	* Integrate support for the newest ez80 ZDSII 5.3.0 toolchain.  From
+	  Gregory Nutt (2019-06-02).
+	* include/nuttx/net/bluetooth.h:  Ignore content if CONFIG_NET_BLUETOOTH is
+	  not set.  This is necessary because bt_hci.h content was previously
+	  commented out because it uses several compiler specific things include
+	  zero-dimensione arrays and uint64_t.  Neither are supported by the C89
+	  ZiLOG ZDS-II compiler.  From Gregory Nutt (2019-06-02).
+	* configs/axoloti:  Adds initial support for the Axoloti sound/music
+	  synthesizer board.  Board is based on STM32F427 SoC.  See
+	  http://www.axoloti.com/.  From Jason Harris (2019-06-02).
+	* arch/z80/src:  Fix ez80 compile problems due to New ZDS-II toolchain and
+	  ongoing bit rot due to non-C89 code creeping into the core OS.  From
+	  Gregory Nutt (2019-06-02).
+	* configs:  Fix included path used in all arch/z80 XDS-II builds (ez80 and
+	  z8).  From Gregory Nutt (2019-06-02).
+	* arch/z16/src:  Replicate build changes make for ez80 and z8 for zneo.
+	  From Gregory Nutt (2019-06-02).
+	* arch/z16/src/z16f/Kconfig and configs/z16f2800100zcog/scripts/Make.defs:
+	  Add support for the lastest 5.2.1 version of the ZDS-II toolchain.  From
+	  Gregory Nutt (2019-06-02).
+	* net/usrsock: Fix debug logs and remove DEBUGASSERT from
+	  usrsockdev_do_request().  In a client mode, socket() will be the first
+	  request for usrsockdev_do_request().  However, in a server mode, the
+	  first request to accepted sockets will be recv() or others which depend
+	  on applications. So I think we should remove this DEBUGASSERT from
+	  usrsockdev_do_request().  From Masayuki Ishikawa (2019-06-03).
+	* arch/arm/src/STM32H7:  Port PWM from STM32  From raiden00pl (2019-06-03).
+	* arch/arm/src/common/up_lwl_console.c:  Add support for a 'Lightweight
+	  Link' protocol between a target and debugger for use when you need a
+	  console but the target doesn't have a spare serial port or other
+	  available resource.  From Dave Marples (2019-06-03).
+	* include/nuttx/signal.h:  Fix a C89 compliance problem that cause the ez80
+	  build to fail.  Empty structure and unions are not accepted by the
+	  compiler.  From Gregory Nutt (2019-06-03).
+	* drivers/net/telnet.c:  Fix a C89 non-compliance that was breaking the
+	  ez80 build.  From Gregory Nutt (2019-06-03).
+	* libs/libc/stdio:  Fix long long usage in all of the newer printf-related
+	  logic:  The selection CONFIG_LIBC_LONG_LONG must be ignored if the
+	  architecture does not support long long types.  From Gregory Nutt
+	  (2019-06-03).
+	* mm/mm_heap/mm_sem.c:  Fix error that occurs when CONFIG_CPP_HAVE_VARARGS
+	  is not defined.  In that case, the arguments to the debug macro will all
+	  be evaluated even though they are not used any variables that are
+	  references must at least be defined.  From Gregory Nutt (2019-06-03).
+	* udp\udp_callback.c:  Fix another C89 compatibility problem.  Empty
+	  initializers are not permitted.  Caused ez80 build failure.  From Gregory
+	  Nutt (2019-06-03).
+	* configs/:  Update configurations for changes to apps/netutils/netinit
+	  configuration.  MAC address configuration was represented by type long
+	  long.  That is a problem for architectures that do not support typle long
+	  long.  Replaces by two long configuration items.  From Gregory Nutt
+	  (2019-06-03).
+	* Fix several ZNeo compile issues.  There are more.  Pthreads:  Fix a could
+	  of places where FAR was added when it is not appropriate.  This matters to
+	  ZNeo which depends on definitions of NEAR and FAR points.  From Gregory
+	  Nutt (2019-06-03).
+	* include/nuttx/wqueue.h:  Allow definitions even if work queues are not
+	  enabled.  This solves build failures when work queues are not enabled.
+	  From Gregory Nutt (2019-06-03).
+	* More ZNeo compile fixes:  include/stdio.h:  Another place where misuse of
+	  FAR makes a difference.  include/nuttx/sched.h:  Be consistent in use of
+	  WDOG_ID type.  ZDS-II doesn't like auto-conversions of struct wdog_s * to
+	  WDOG_I (which is type struct wdog_s *).  From Gregory Nutt (2019-06-03).
+	* Various fixes to get a clean compile with the SDCC compiler.  Compile is
+	  'almost' clean.  From Gregory Nutt (2019-06-03).
+	* Add initial support for the MakerLisp eZ80 board.  Ref:
+	  https://makerlisp.com/  From Gregory Nutt (2019-06-04).
+	* arch/arm/src/cxd54xx:  Adds (1) the HW pin configuration, (2) GPIO
+	  support for cxd56xx, (3) GPIO interrupts, (4) clock support, (5) PMIC
+	  (Power management integrated circuit) supportm (6) add a simple FIFO
+	  schedulier that minimizes overhead, (6) Inter Core Communication.  From
+	  Alin Jerpelea (2019-06-05).
+	* arch/arm/src/cxd54xx:  Add Package Configuration. The CXD56xx can come in
+	  FCBGA 185 pin or WLCSP 100 pin package.  For each package we have to pick
+	  the right pin setup.  The default configuration is set to FCBGA 185 pin
+	  package  From Alin Jerpelea (2019-06-05).
+	* drivers/sensor, include/nuttx/sensors:  Add support for AS726X spectral
+	  sensor  From Fabian Justi (2019-06-05).
+	* configs/nucleo-l476rg/src/stm32_appinit.c:  (1) Add I2C tool to board
+	  init, (2) Add support for AS726X spectral sensor  From Fabian Justi
+	  (2019-06-05).
+	* arch/arm/src/cxd54xx: (1) Add basic support for USB connectivity, (2) add
+	  SDHCI driver for the cxd56xx  From Alin Jerpelea (2019-06-05).
+	* configs/makerlisp/src/ez80_spi.c:  Add hooks needed by SPI driver.  Move
+	  SPI MMC/SD chip selected configuration from ez80_lowinit.c to here as is
+	  done in other NuttX architectures.  This enables support for multiple
+	  devices on the SPI bus.  From Gregory Nutt (2019-06-05).
+	* configs/:  Rename ZDS-II start files from xxx_lowinit.c to xxx_boot.c;
+	  rename board initialization logic from xxx_lowinit() to
+	  xxx_board_initialize().  These changes make the ZDS-II configurations
+	  more similar to board initialization conventions to used for other
+	  architectures.  From Gregory Nutt (2019-06-05).
+	* Documentation/NuttXCCodingStandard.html:  Add a brief section summarizing
+	  the major differences between the NuttX C and C++ coding standards.  This
+	  is a stop-gap measure in lieu of having a real C++ coding standard.  From
+	  Gregory Nutt (2019-06-05).
+	* drivers/sensors/as726x.c Fix little change from tools/indent.sh  From
+	  Fabian Justi (2019-06-06).
+	* arch/z80/src/ez80/Make.defs:  Fix some backward conditional loic  From
+	  Gregory Nutt (2019-06-07).
+	* arch/z80/src/ez80:  Integrate and verify the RTC driver  From Gregory
+	  Nutt (2019-06-08).
+	* nuttx/arch/z80/src:  To properly follow the coding standard, the z80
+	  architecture common should up_mmuinit should be called
+	  z80_mmu_initialize; the z80 architecture common should up_loweserialinit
+	  should be called z80_lowserial_initialize; the z80 architecture common
+	  should up_serialinit should be called z80_serial_initialize; the z80
+	  architecture common should up_doirq should be called z80_doirq.  From
+	  Gregory Nutt (2019-06-08).
+	  configs/z80sim/src/z80_serial.c:  Remove unused function
+	  up_earlyserialinit().  From Gregory Nutt (2019-06-08).
+	  arch/z80/src/common:  up_addregion() must be prototyped in
+	  nuttx/mm/mm.h, not up_internal.h.  From Gregory Nutt (2019-06-08).
+	* arch/z80/src:  Rename up_doirq.c and up_internal.h to z80_doirq.c and
+	  z80_internal.h for better consistency with the naming conventions  From
+	  Gregory Nutt (2019-06-09).
+	* arch/arm/src/stm32/hardware/stm32f1xxx_pinmap.h: fix names for
+	  complementary PWM outputs  From raiden00pl (2019-06-10).
+	* libs/libc/time/lib_gmtimer.c:  Spurious reorganization of a loop to work
+	  around and ZDD-II internal compiler error.  Might be a little bigger now,
+	  but is also probably a more structured use of C.  From Gregory Nutt
+	  (2019-06-10).
+	* arch/arm/src/cxd56xx: add Power Management support  From Alin Jerpelea
+	  (2019-06-10).
+	* configs: Fix mac address settings for rndis.  Recently
+	  CONFIG_NETINIT_MACADDR_2 and CONFIG_NETINIT_MACADDR_1 were newly
+	  introduced instead of CONFIG_NETINIT_MACADDR.  This PR conforms to this
+	  change.  From Masayuki Ishikawa (2019-06-11).
+	* arch/arms/src/cxd56xx: (1) Add syscontrol, (2) Add the function to change
+	  the clock speed, (3) Add pinctrl and clock ctrl functionality.  From Alin
+	  Jerpelea (2019-06-11).
+	* stm32/stm32_pwm.c, STM32H7/stm32_pwm.c: fix pulsecount for the number of
+	  counts greater than 128  From raiden00pl (2019-06-12).
+	* configs/spresense:  (1) We are using the framework to initialize the CPU,
+	  (2) Enable PowerManager on spresense board, (3) Initialize the UART
+	  interfaces, (4) Enable clock management using the cxd56 framework, (5)
+	  Use timerisr on the spresense board, (6) Enable USBDEV on Spresense
+	  board, (7) Enable SD Card support on spresense board, (8) Enable Mass
+	  Storage on Spresense board  From Alin Jerpelea (2019-06-12).
+	* configs/makerlisp:  Add Smart Flash Programmer project.  From Gregory
+	  Nutt (2019-06-12).
+	* ina3221: Adds INA3221_I2C_ADDRx macro helpers.  From Anthony Merlino
+	  (2019-06-13).
+	* drivers/mmcsd: Fixes bug where thread gets deadlocked due to recursive
+	  call and addresses comment regarding events.  When initializing the
+	  MMCSD, if we are being told there is a card, but we fail to initialize
+	  it, we should not re-register for an insertion event as this will
+	  immediately cause us to call in again. Instead, we should register for a
+	  removal event and wait for the card to be removed and re-inserted.  From
+	  Anthony Merlino (2019-06-13).
+	* arch/arm/src/cxd56xx: Fix ep0 out packet handling in cxd56_usbdev.c. This
+	  change fixes to handle ep0 out packet which exceeds EP0_MAXSIZE.  For
+	  example, 76 bytes of out packet is sent from rndis host during rndis
+	  negotiation and finally the packet is split into two out packets (64
+	  bytes out packet + 12 bytes out packet). To handle these packets, actual
+	  ep0reqlen is stored during ep0 out setup stage, and if all out packets
+	  are received, it dispatches to cxd56_ep0setup(), otherwise, it sets up
+	  the internal USB DMA to receive remaining out packets.  From Masayuki
+	  Ishikawa (2019-06-13).
+	  configs/spresense: Add support for rndis configuration.  From Masayuki
+	  Ishikawa (2019-06-13).
+	* arch/arm/src/cxd56xx: Add SPI, DMA, and RTC support
+	  configs/spresense:  Enable RTC functionality on spresense board  From
+	  Alin Jerpelea (2019-06-13).
+	* arch/arm/src/stm32l4: if SRAM3 is used as heap, do not power it off in
+	  stop 2 mode.  From Juha Niskanen (2019-06-13).
+	* configs/nucleo-l432kc:  Shorten some long lines, fix i2c pinout in
+	  l432kc, add support for testing the ina219 current sensor.  From
+	  Sebastien Lorquet (2019-06-13).
+	* configs/spresense:  Enable SPI Flash
+	  arch/arm/src/cdx56xx:  (1) Group all CXD56xx Options in one menu, (2) Add
+	  Storage Options menu and Peripheral Support comment, (3) Add SPI Flash
+	  support  From Alin Jerpelea (2019-06-13).
+	* configs/stm32f4discovery/src/stm32_romfs_initialize.c:  Missing colon in
+	  declaration of local variable.  From Phil Coval (2019-06-13).
+	* configs/nucleo-144: Add ROMFS support.  Image was generated using
+	  genromfs tool.  Tested on Nucleo-f767zi.  From Phil Coval (2019-06-13).
+	* STM32H7 Serial: Fix error when SINGLEWIRE or
+	  CONFIG_STM32H7_SERIALBRK_BSDCOMPAT defined.  From David Sidrane
+	  (2019-06-13).
+	* STM32H7 Timer:  Fixed compile errors with TIM13, TIM14, TIM7.  From David
+	  Sidrane (2019-06-13).
+	* STM32H7 ADC:  Added ADC Driver, ADC clocking.  From David Sidrane
+	  (2019-06-13).
+	* STM32H7x3:  Added ADC pins to pin map.  From David Sidrane (2019-06-13).
+	* configs/nucleo-h743zi: Add ADC support.  From David Sidrane (2019-06-13).
+	* drivers/serial/serial.c:  Limit the number of times that the poll
+	  semaphore is incremented.  From Dave Marples (2019-06-13).
+	* arch/arm/src/cxd56xx: Change cxd56_gpioint_config to handle argument.
+	  From Masayuki Ishikawa (2019-06-14).
+    * configs/spresense: Apply API change of cxd56_gpioint_config().  From
+	  Masayuki Ishikawa (2019-06-14).
+	* arch/arm/src/cxd56xx:  Add support for PWM.  Add Power Management PROCFS
+	  support. Add Timer driver.  Add watchdog timer support..  From Alin Jerpelea (2019-06-14).
+	* configs/spresense: Add SPI configuration for spresense board. Enable PWM
+	  support on spresense board;  The powermanager procfs is disabled by
+	  default and need to be enabled by the CONFIG_CXD56_PM_PROCFS option.
+	  Timers can be used on the spresense board.  Watchdog timer support also
+	  added.  From Alin Jerpelea (2019-06-14).
+	* configs/omnibusf4/src/stm32_bringup.c:  Correct naming of a configuration
+	  variable for ROMFS.  From Phil Coval (2019-06-15).
+	* configs/stm32f4discovery/src/stm32_bringup.c:  Correct naming of a

+	  From Alin Jerpelea (2019-06-20).
+	* drivers/usbhost/usbhost_composite.c:  I'm working on a CDC/ECM  driver
+	  and in my driver's usbhost_cfgdesc() function I need access to the
+	  class-specific descriptors. Currently these are not available if the
+	  interface is part of a composite device, since only interface and
+	  endpoint descriptors are copied by usbhost_copyinterface().  This commit
+	  will also copy any class-specific interface descriptors for use in
+	  downstream class drivers.  NOTE: There's one change that might be
+	  incorrect, where I skip interfaces with zero endpoints. I did this
+	  because my device has two consecutive interface descriptors with the same
+	  interface number, one for altsetting 0 with no endpoints, and another for
+	  altsetting 1 with 1 endpoint.  The loop was aborting due to finding two
+	  interface descriptors back-to-back.  From Adam Porter (2019-06-21).
+	* STM32F7 GPIO:  Add GPIO driver.  Code is inspired from stm32f3discovery
+	  and nucleo-l476rg platforms.  Tested on Nucleo-F767ZI.  From Phil Coval
+	  (2019-06-21).
+	* drivers/usbhost/usbhost_composite.c:  The cfgdesc pointer was initialized
+	  after the buffer had been advanced, so it was not pointing where it
+	  should. The totallen operations at the end of the function ended up
+	  overwriting memory belonging to the first copied interface descriptor.
+	  From Adam Porter (2019-06-22).
+	* configs/pnev5180b:  Add usbnsh configuration.  This is basically the same
+	  as the 'nsh' defconfig, but uses CDC/ACM as the NuttShell console
+	  device.  From Michael Jung (2019-06-22).
+	* STM32 USB OTG FS/HS Host:  In stm32_ctrlout() in the HS and FS host
+	  drivers, the data buffer isn't sent. This patch passes the buffer and
+	  buflen to the stm32_ctrl_senddata() function.   With this change, I am
+	  able to send MBIM control messages to my USB modem, and read the
+	  response.  From Adam Porter (2019-06-23).
+	* configs/makerlisp/src/sd_main.c:  Add a tiny FLASH-resident loader that

+	  character devices.  Add battery gauge and battery charger drivers.  Add
+	  SPI-based SP card support.  From Alin Jerpelea (2019-06-25).
+	  configs/spresense:  Add use o the CXD56_I2C_DRIVER to register the
+	  /dev/i2c character devices.  Enable battery gauge and battery charger
+	  support.  From Alin Jerpelea (2019-06-25).

+	* arch/arm/src/samd2l2/hardware/samd_tc.h:  Correct register bit field
+	  definitions used with TC_CTRLBCLR and TC_CTRLSET registers.  From Bernd
+	  Walter (2019-06-26).
+	* libs/libc/misc/Make.defs:  For platforms whose CPP tool does not support
+	  a variable number arguments to pre-processor macros, we may still need to
+	  build the debug functions even when CONFIG_DEBUG_FEATURES is not
+	  selected.  For example, __alert() may be needed if CONFIG_ARCH_STACKDUMP
+	  is set.  From Gregory Nutt (2019-06-26).
+	* configs/makerlisp:  Add an sdboot configuration that will load .hex files
+	  from the SD card.  From Gregory Nutt (2019-06-26).

+	* configs/olimex-stm32-e407/src:  Change initialization to match the way it
+	  is done with other boards.  From Gregory Nutt (2019-06-28).
+	* sched/semaphore/sem_holder.c:  Fix a bad assertion.  The comments state
+	  correctly that we cannot make any assumptions about the number of holders
+	  of the semaphore, yet the code asserts if there are any holders.  This
+	  makes the code behave closer to what the comments say.  From Gregory Nutt
+	  (2019-06-28).
+	* configs/pnev5180b/nsh-cdcecm/defconfig: CDC/ECM requires SCHED_LPWORK
+	  From Gregory Nutt (2019-06-29).
+	* Various Kconfig files:  Kconfig files should not select SCHED_WORKQUEUE
+	  since that is really only is only the logical OR if SCHED_LPWORK and
+	  SCHED_HPWORK.  Selecting it has no effect other than to produce an
+	  erroneous configuration.  From Gregory Nutt (2019-06-29).
+	* nrf24l01:  Fix PIPENO/PKTLEN bitmask in rx fifo header.  In RX fifo
+	  header, the first byte should use 5 lsb to store PKTLEN and 3 msb to
+	  store PIPENO. However, FIFO_PIPENO_SHIFT was set to 4 which causes the
+	  lsb of pipe number to interfere with the received packet size stored in
+	  the fifo.  This fix rx corruption when using pipe number > 0.  From
+	  Federico Braghiroli (2019-06-29).
+	* configs/pnev5180b/usbnsh-cdcecm:  This new configuration includes a USB
+	  Composite Device with both CDC/ACM and CDC/ECM.  NuttShell provides a
+	  terminal via CDC/ACM.  A network interface (eth0) is provided via
+	  CDC/ECM.  From Michael Jung (2019-06-29).
+	* tools/nxstyle.c:  Tool depends on the file under test containing "Private
+	  Functions" or "Public Functions" block comments.  Emit an error is
+	  neither are present in a C source.  From Gregory Nutt (2019-06-29).
+	* tools/nxstyle.c:  Bandaid-up logic that detects left brackets on the same
+	  line in global structure/enumeration types and initializers.  From
+	  Gregory Nutt (2019-06-29).
+	* arch/arm/src/imxrt/imxrt_ehci.c:  Add i.MXRT ECHI driver.  From Dave
+	  Marples (2019-06-29).
+	* include/nuttx/net/netconfig.h:  Fix warning '__MAX_UDP_MSS macro
+	  redefined'  From Adam Porter (2019-06-30).
+	* configs/stm32f4discovery/kernel/Makefile:  Fix a problem with undefined
+	  symbol 'abort' from GCC library.  Fix by moving libgcc into recursive
+	  archive group between --start-group and --end-group.  Other
+	  kernel/Makefiles suffer from this same issue  From Gregory Nutt
+	  (2019-06-30).
+	* tools/nxstyle.c:  Fix error in conditional logic that was preventing
+	  detection bad brace alignment.  Add logic to handle alignment of braces
+	  in data initializators which following slightly different indentation
+	  rules.  From Gregory Nutt (2019-06-30).
+	* tools/nxstyle.c:  No warning for declarations that begin in column 1
+	  within 'extern "C"'.  This is because the 'extern "C"' is conditioned on
+	  __cplusplus so the declarations are not normally indented.  From Gregory
+	  Nutt (2019-06-30).
+	* libs/libc/netdb: Implemented the netdb functions getnameinfo(),
+	  getservbyport(), and getservbyport_r().  From Michael Jung (2019-06-30).
+	* configs/pnev5180b/src/lpc17_romfs:  pnev5180b/src/lpc17_romfs: Automount
+	  baked-in ROMFS image.  Includes support for linking a binary ROMFS image
+	  into the nuttx executable and for mounting it during board bringup.  From
+	  Michael Jung (2019-06-30).
+	* drivers/usbdev/usbmsc:  Fix usbmsc_exportluns declaration.  Fixes the
+	  following error "...undefined reference to `usbmsc_exportluns'".  From
+	  Alin Jerpelea (2019-07-01).
+	* configs/spresense:  Register the procfs in the NSH configuration.  This
+	  is a configuration change in sync with the other ones.  Enable
+	  READLINE_CMD_HISTORY, enable by default SPI 4 and 5, and enable SPI to
+	  keep all configurations in sync.  From Alin Jerpelea (2019-07-01).
+	* net/inet: Fix tcp active close in inet_close.c.  In previous
+	  implementation, FIN packet was not sent when a socket is actively closed
+	  (e.g. telnetd or webserver) without SO_LINGER.  This issue happens
+	  because the socket closing sequence waits for the status.cl_sem only if
+	  lingering timeout is set. However, in many server use-cases, SO_LINGER is
+	  not usually set and even in these cases, FIN packet must be sent
+	  correctly.  This changes the logic in inet_close.c so that it can wait
+	  for status.cl_sem regardless of SO_LINGER. Instead, if SO_LINGERis set,
+	  it waits for the semaphore with timeout option.  From Masayuki Ishikawa
+	  (2019-07-01).
+	* net/inet/inet_close.c:  Last change removed SO_LINGER socket option
+	  functionality.  SO_LINGER was always enabled is CONFIG_NET_SOLINGER was
+	  selected.  This change implements a proper version of SO_LINGER.  It is
+	  based on new logic to drain the buffered TX data, integrated with network
+	  event notification system.  Supports notification when UDP or TCP write
+	  buffer becomes empty.  From Gregory Nutt (2019-07-01).
+	* configs/spresense:  Add support for MSC and USB Composite device.  Adds
+	  usbmsc configuration.  Spresense board does not have buttons and but a
+	  template for gpio buttons that can be connected on the external header
+	  From Alin Jerpelea (2019-07-02).
+	* drivers/wireless: Fix a passive close when sending a packet in gs2200m.c
+	  From Masayuki Ishikawa (2019-07-03).
+	* arch/arm/src/tiva: Add a workaround for tiva with qemu.   With qemu,
+	  tiva_ifup() hangs because ethernet link status can not be set correctly.
+	  This PR is a workaround to avoid this issue.  From Masayuki Ishikawa
+	  (2019-07-03).
+	* arch/arm/sr/cxd56xx:  Add driver for hardware image processor device to
+	  enable the hardware image processor set CXD56_GE2D=true.  From Alin
+	  Jerpelea (2019-07-03).
+	* drivers/lcd:  Add ILI9340 LCD Single Chip Driver.  Required LCD driver
+	  settings:  LCD_MAXCONTRAST should be 255, but any value >0 and <=255 will
+	  be accepted.  LCD_MAXPOWER should be 1:  0=off, 1=on.  From Alin Jerpelea
+	  (2019-07-03).
+	* drivers/lcd:  Add JDI LPM013M091A LCD Driver.  From Alin Jerpelea
+	  (2019-07-03).
+	* configs/spresense:  Add suport for lpm013m091a LCD, add support for
+	  ili9340 LCD, add a new configuration to support an LCD.  From Alin
+	  Jerpelea (2019-07-03).
+	* arch/arm/src/stm32f7/stm32_serial.c:  This adds the ability to invert and
+	  swap RX/TX on STM32F7 UARTs.  I added the TIOCGINVERT as well to reserve
+	  the IOCTL number, but did not implement it. This is the same as for
+	  TIOCGSINGLEWIRE.  From Beat Küng (2019-07-03).
+	* arch/arm/src/imxrt/imxrt_usdhc.c:  Implements SDIO and Multi-card support
+	  for i.MX RT.  From Dave Marples (2019-07-03).
+	* STM32H7 Serial:  Add TIOCSINVERT and TIOCSSWAP ioctls.  Ensure
+	  TIOCSSINGLEWIRE is atomic and UE disabled.  From Beat Küng (2019-07-03).
+	* STM32L4 Serial:  Add TIOCSINVERT and TIOCSSWAP ioctls
+	* i.MX RT:  Add TIOCSINVERT ioctls.  From Beat Küng (2019-07-03).
+	* arch/arm/src/am335x:  Add clock module registers definition.  Switch to
+	  DMTIMER1 for systick.  From Petro Karashchenko (2019-07-03).
+	* arch/arm/src/cxd56xx: Fix DMA initialization in cxd56_dmac.c.
+	  up_dma_initialize() must be used instead of up_dmainitialize().  From
+	  Masayuki Ishikawa (2019-07-04).
+	* drivers/wireless:  Introduce CONFIG_WL_GS2200M_SPI_FREQUENCY.  Also,
+	  changed usleep(100) to up_udelay(100) to avoid invalid response.  From
+	  Masayuki Ishikawa (2019-07-04).
+	* configs/spresense/wifi:  Improve performance for webserver:  (1) Enable
+	  SPI DMA for both TX and RX, (2) Increase SPI clock speed from 4MHz to
+	  10MHz, (3) Increase buffer size for sendfile() from 512B to 1KBm abd (4)
+	  Enable sendfile() for webserver.  From Masayuki Ishikawa (2019-07-04).
+	* tools/mkexport.sh:  The mcu sub-directory chip/ was renamed to hardware/
+	  in late May of 2019.  The mkexport.sh script that copies these files was
+	  not updated, however, until now.  Noted by Alin Jerpelea.  From Gregory
+	  Nutt (2019-07-04).
+	* drivers/video:  Add basic Video Stream and Capture implementation based
+	  on the spresense SDK code release  From Alin Jerpelea (2019-07-04).

+	  From Gregory Nutt (2019-07-07).
+	* arch/arm/src/imxrt:  Implements USDHC1 & 2 selection on the imxrt. If
+	  only one port is active (either 1 or 2) it will always be numbered as 0,
+	  if both are active then USDHC1 will be number 0, USDHC2 will be 1.  From
+	  Dave Marples (2019-07-07).
+	* video/edid/edid_sort.c:  Add logic to sort video modes by how close they

+	* configs/nucleo-h743zi/src/stm32_spi.c:  Correct typos in function
+	  naming.  From Jonathan Richner (2019-07-08).
+	* arch/arm/src/am335x/hardware/am335x_lcd.h:  Fix a few typos.  Add things
+	  needed by the LCDC driver.  From Gregory Nutt (2019-07-08).
+	* This change brings in an initial LCD driver sof the AM335x architecture.
+	  This is a work in progress and so depends on EXPERIMENTAL.  The code is
+	  nearly compete, missing some clock configuration settings.  It does yet
+	  even compile properly.  From Gregory Nutt (2019-07-08).
+	* arch/arm/src/am335x:  Add logic to map the framebuffer to a non-cached,
+	  non-buffered memory region.  From Gregory Nutt (2019-07-08).
+	  arch/arm/src/am335x:  Remove struct am335x_fbinfo_s.  Replaced with
+	  configuration settings that provide the same information.  From Gregory
+	  Nutt (2019-07-08).
+	* arch/arm/src/am335x/am335x_sysclk.c:  Add a function to return a
+	  frequency of the system clock.  From Gregory Nutt (2019-07-08).
+	* arch/arm/src/am335x/am335x_lcdc.c:  Add logic to get/set the module
+	  reference clock.  Still one more clocking interface to to.  From Gregory
+	  Nutt (2019-07-08).
+	* configs/beaglebone-black/lcd/defconfig:  Add a configuration for bringing
+	  up the LCDC driver.  From Gregory Nutt (2019-07-08).
+	* tools/:  Add flash_writer for cxd56 boards.  This flash writter is using
+	  the xmodem for firmware transfer for flashing please use:
+	  'tools/flash_writer.py -s -c /dev/ttyUSB0 -d -b 115200 -n nuttx.spk'
+	  From Alin Jerpelea (2019-07-09).
+	* Update COPYING file.  Tools in the tools/ directory are not intended for
+	  binary redistribution and may not all conform to BSD licensing.  From
+	  Gregory Nutt (2019-07-09).
+	* On the LPC1769 there are two 16 KiB AHB SRAM blocks, which are mapped
+	  back to back at physical address 0x2007C000 and 0x20080000 (i.e. right
+	  below and right above a 512 KiB boundary).  Memory from those two blocks
+	  is considered continuous when assigned to a heap.  In the protected build
+	  mode, when the memory protection unit is used, though, it must be split
+	  into two MPU regions.  This is because MPU regions must be naturally
+	  aligned, and the 32KiB continuous address space of the two 16KiB AHB SRAM
+	  blocks does not start at an address divisible by 32KiB.  The only other
+	  configurations that use protected build mode on lpc17xx are currently
+	  open1788/knsh and open1788/knxterm.  The LPC1788 has the AHB SRAM blocks
+	  mapped more sanely (from an MPU region point of view), which is probably
+	  why no problems emerged here.  Both still compile with my change and
+	  other than wasting an MPU region (which would otherwise remain unused)
+	  should work fine.  That said, I have no hardware to confirm.  From
+	  Michael Jung (2019-07-09).
+	* configs/pnev5180b/knsh:  Add PROTECTED mode configuration with
+	  NuttShell.  From Michael Jung (2019-07-09).
+	* configs/beaglebone-black/src/am335x_lcd.c:  Framework (only) for TDA19988
+	  and LCD support for Beaglebone Black.  Can't use TDA19988 yet because
+	  there is no I2C driver.  In the mean time, support LCD initialization
+	  using a fixed, configurable video mode.  From Gregory Nutt (2019-07-09).
+	* arch/arm/src/am335x/hardware/am335x_prcm.h:  Rename am335x_cm.h to
+	  am335x_cm.h.  From Petro Karashchenko (2019-07-09).
+	* arch/arm/src/am335x: Changes related to Control Module  From Petro
+	  Karashchenko (2019-07-09).
+	* arch/arm/src/am335x/Kconfig:  Remove unused configuration settings left
+	  over from original copy-paste.  From Gregory Nutt (2019-07-09).

+	  vfork() syscall proxy and stub to the logic used for vfork() itself.
+	  From Michael Jung (2019-07-10).
+	* configs/olimex-stm32-e407/src/stm32_spi.c:  Add SPI initialization
+	  logic.  From uan Flores (2019-07-10).
+	* drivers/sensors/vl53l1x.c:  Added support for VL53L1X TOF sensor.  From
+	  Juan Flores (2019-07-10).
+	* drivers/lcd/tda19988.c:  Now uses the new common videomode structure of
+	  include/nuttx/video/videomode.h as do other video components.  From
+	  Gregory Nutt (2019-07-10).
+	* video/, include/nuttx/video/videomode.h:  Separate EDID and from
+	  videomode management.  They really are separate things.  From Gregory
+	  Nutt (2019-07-10).
+	* video/edid:  Add debug functions to dump the EDID and videomode content.
+	  From Gregory Nutt (2019-07-10).
+	* viedo/videomode:  Rename video/edid to video/videomode.  There is more
+	  there than just EDID but it is all basically videomode stuff.  From
+	  Gregory Nutt (2019-07-10).
+	* video/videomode/vesagtf.c:  Bring VESA Generalized Timing Formula (GTF)
+	  from FreeBSD.  From Gregory Nutt (2019-07-10).
+	* video/videomode/videomode_lookup.c:  At some additional lookups from
+	  FreeBSD.  Not currently used in NuttX so ifdef'ed out for now.  From
+	  Gregory Nutt (2019-07-10).
+	* configs/spresense:  Enable internal flash storage for spresense boards.
+	  The smartfs flash is mounted under /mnt/spif folder.  From Alin Jerpelea
+	  (2019-07-11).
+	* configs/spresense:  For compatibility with SDK we need to change the
+	  USER_ENTRYPOINT in all configurations to spresense_main().  From Alin
+	  Jerpelea (2019-07-11).
+	* include/cxx/cstddef:  Add C11++ std::nullptr_t  From junmin-kim
+	  (2019-07-11).
+	* configs/olimex-stm32-e407:  Added BMP180 initialization and a
+	  configuration to test the BMP180.  From Juan Flores (2019-07-11).

+	  ID.  From Daniel P. Carvalho (2019-07-11).
+	* arch/arm/src/lpc17xx_40xx and configs/:  Add support for LPC40xx family
+	  chips.  Renamed LPC17XX to LPC17XX_40XX in directory, configuration, file
+	  names, etc., as appropriate.  Corrected a few peripheral definitions and
+	  pin functions for the LPC17xx family.  Added configuration options, chip
+	  definitions, and additional pin functions for the LPC40xx family.
+	  configs/lpc4088-devkit/:  Added board configuration for Embedded Artists
+	  LPC4088 Developer's kit.  From jjlange (2019-07-11).
+	  configs/lpc4088-devkit/:  Added board configurations for Embedded Artists
+	  LPC4088 Quickstart board.  From jjlange (2019-07-11).
+	* include/fixedmath.h:  Regarding the single precision float to/from fixed
+	  point conversions in fixedmath.h, I believe the floating point literals
+	  should be appended with the letter 'f' to avoid (expensive) conversions
+	  from single to double precision, and thereby also avoid (expensive if
+	  done in SW) double point arithmetic (which is what is happening upon
+	  inspection of my disassembly).  From rajan gill (2019-07-11).
+	* arch/arm/src/lpc11xx, arch/arm/include/lpc11xx,
+	  configs/lpcxpresso-lpc1115:  Support for the LPCXpresso-LPC1115 and for
+	  the LPC1115 architecture in general was removed after NuttX-7.30. The
+	  LPC11 port was never really used (to my knowledge) and was no longer
+	  supported. A snapshot of the port is still available in the Obsoleted
+	  repository. It can be brought back into the main repository at any time
+	  if anyone is willing to provide support for the architecture.  From
+	  Gregory Nutt (2019-07-11).
+	* configs/spresense: Fix and refactor cxd56_leds.c  From Masayuki Ishikawa
+	  (2019-07-12).
+	* arch/arm/src/cxd56xx:  Add GNSS device, add Geofence Support, add UART0
+	  interface. UART0 is an interface with hardware flow control in the

+	  Nutt (2019-07-18).
+	* configs/makerlisp/src/ez80_boot.c:  The VGA display controller and
+	  keyboard controller come up by default emulating a terminal with 'newline
+	  mode' on.  That is newlines expance to carriage-return, newline.  This
+	  patch turns that mode off.  From Gregory Nutt (2019-07-20).
+	* configs/tm4c1294-launchpad/tools/oocd.sh:  Fix syntax error.  From Nathan
+	  Hartman (2019-07-20).
+	* ched/sched/sched_waitpid.c:  In waitpid, remember to grab the exited
+	  child ptr.  After being unblocked in waitpid, the child pointer might be
+	  NULL.  Modify to use group_exitchild to get the pointer of recent exited
+	  child.  From Yang ChungFan (2019-07-20).
