The MMU must be enabled during mapping changes and TLB invalidations.
When this is not the case, TLB updates do not occur correctly in all
cases. This is especially apparent when changing a block entry to a
table entry when remapping small memory ranges in an otherwise
contiguous block.
Do not warn about excessive shifts in imported Xilinx driver code when
building with the ILP32 ABI. The two instances of this warning produce
the desired effect of setting the upper address bits to 0.
This allows any builds targeting an installed RTEMS BSP to override
headers in the installed BSP reliably, including headers previously
installed by that or other builds. This includes applications, network
stacks, libraries, and any other builds.
Closes#4896
This patch includes the spec/build options for the riscv kendrytek210
BSP variant. It includes options to allow the frdme310arty console
UART to be used on multiple BSPS, device tree options, memory
options, and other required options for the variant.
Updates #4876
This patch adds support for the Kendryte K210 RISC-V BSP variant.
The SoC uses the existing Interrupt Controller, Timer, and console UART.
It only needs SoC specific initialization and an embedded device tree binary
similar to the polarfire SoC BSP.
Updates #4876
This patch adds the k210 device tree source and the corresponding
device tree blob encoded in the header which is used for the
embedded device tree blob for the Kendryte K210 BSP variant.
Updates #4876
The existing include path only works from inside the RTEMS build. This
fixes the include path to work both in the RTEMS build and with builds
of external apps since this file gets installed with the BSP.
Use the mtimecmp from the PLIC/CLINT initialization in the clock driver. This
register is defined by the device tree and does not assume a fixed mapping.
In SMP configurations, check that we run on a configured processor. If not,
then there is not much that can be done since we do not have a stack available
for this processor. Just loop forever in this case. Do this in assemlby to
ensure that no stack memory is used.
This adds write buffer and bad block support required for JFFS2
operation on NAND devices. This also adds the minor modifications
necessary for RTEMS support in the Linux header stubs and in wbuf.c.
Memory and NOR backed applications should experience no difference in
operation since they do not expose the callbacks required for write
buffer support.
The kernel space parts of standard system header files were protected
against misuse by a preprocessor error directive. This approach does
not work well with tools such as Doxygen. Provide the kernel space
items only if the required defines are present.
