Add dedicated NEON implementations for mutually aligned medium and long memcpy copies when building with __ARM_NEON__. These paths use NEON multi-register loads and stores while preserving the existing VFP implementation for non-NEON VFP configurations.
NEON builds also define USE_VFP, so select the NEON implementation explicitly before falling back to VFP. Apply the same aligned-copy optimization to the armv7-a, armv7-r, and armv8-r implementations.

When CONFIG_DISABLE_PTHREAD=y, HAVE_GROUP_MEMBERS is undefined and
group_leave() unconditionally calls group_release() for every exiting
thread. This destroys the shared g_kthread_group resources (mutex,
fdlist, task_info) while other kernel threads are still using them,
causing use-after-free crashes.
Fix by checking TCB_FLAG_TTYPE_KERNEL in group_leave() before calling
group_release(), so the entire release path is skipped for kernel
threads. This is safe because g_kthread_group is statically allocated
and its lifetime is the entire system.

current_usec() returns a uint64_t, but it used TICK2USEC(timebase)
to convert scheduler ticks to microseconds. On 32-bit clock_t builds,
TICK2USEC() performs the multiplication in 32-bit arithmetic before the
result is widened.
With CONFIG_USEC_PER_TICK=10000, this wraps after about 71.6 minutes:
UINT32_MAX / 1000000 ~= 4294 seconds
After the wrap, up_timer_gettick() can report time near zero again. This
can leave absolute watchdog timeouts, such as those used by usleep() /
clock_nanosleep(), waiting for a tick value that will not be reached until
the 32-bit scheduler counter wraps.
Cast timebase to uint64_t before multiplying by USEC_PER_TICK so
current_usec() remains monotonic across the 32-bit microsecond boundary.

bluetooth_sendto() uses netdev_findbyindex(conn->bc_ldev + 1) to find
the Bluetooth network device for an HCI socket. netdev_findbyindex
searches by global interface index, but bc_ldev is a 0-based count of
Bluetooth devices only — it bears no fixed relationship to the global
interface index. If any netdev other than a Bluetooth device is
registered before it (e.g. loopback or Ethernet), the Bluetooth device
will not be at global index bc_ldev + 1 and the lookup will return NULL
or the wrong device.
Fix this by replacing netdev_findbyindex with a netdev_foreach walk
using a small callback (bluetooth_dev_byidx_callback) that counts only
NET_LL_BLUETOOTH devices and returns the bc_ldev-th one, regardless of
what else is registered or in what order.

Normalizes configurations after removal of some app-related init config
options due to simplification of NuttX init.
Signed-off-by: Matteo Golin <matteo.golin@gmail.com>
The host interrupt callback was incorrectly using the wrong IRQ for
disconnected. In host mode the same IRQ is used for connect/disconnected
and it must check a status bit to know which one.
When a USB device was unplugged, the host channels were free'd,
but if they happen to be mid-transfer, that transfer was never cancelled
so the USB hardware might still be trying to perfrom a transfer after
was free'd. Fixed by cancelling any transfers on free.

This commit fixes a regression introduced by
89df084b0e. That commit
added a check to ensure iov_base is not NULL, assuming NULL
always represents an inaccessible address.
However, in CONFIG_BUILD_KERNEL mode where CONFIG_ARCH_TEXT_VBASE
is set to 0, address zero is a valid virtual address for the
user-space text segment. The previous check caused libelf to
fail with -EFAULT when attempting to load ELF program headers
into the base of the user address space.
This patch wraps the safety check in a conditional to ensure it is
only executed when address zero is not considered a valid
executable base.

Use GPIO_MODE_INPUT for STM32F1 pinmap entries that are configured as
GPIO_INPUT instead of carrying GPIO_MODE_2MHz.
For STM32F1 the MODE field selects output speed only for output or
alternate-function output pins. stm32_configgpio() forces input pins to
input mode regardless of the encoded MODE bits.
From arch/arm/src/stm32/stm32_gpio.c:
311 /* Decode the mode and configuration */
312
313 regval = getreg32(cr);
314
315 if (input)
316 {
317 /* Input.. force mode = INPUT */
318
319 modecnf = 0;
320 }
321 else

325 modecnf = (cfgset & GPIO_MODE_MASK) >> GPIO_MODE_SHIFT;
