Includes a Mini-UART NSH console for the 4B, tested on the 4GB RAM
model. Part of an I2C driver which can only read, boiler-plate for a SPI
driver, and a GPIO driver with limited pins. Some tools are present for
automatically fetching the boot files and creating the `config.txt` file
based on selected Kconfig options.
- Add support for the IMX95LPD5EVK-19 evaluation kit (M7 core only)
- Firmware can be executed from ITCM, DDR or NOR flash
- configurations:
'nsh' A minimal configuration that only enables nsh shell
on a UART
'rpmsg' This configuration is similar to nsh but in addition
it offers the Remote Processing Messaging (RPMsg) service to
enable heterogeneous inter-core communication.
Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

After https://github.com/apache/nuttx/pull/15075, the size of the
stack size has decreased 8 bytes and the init stack size for the
rv-virt:citest defconfig was near its full capacity, which lead to
crashing the `ps` command. The init stack size for this defconfig
was increased from 2048 to 3072 to avoid stack overflow.
reason:
svc call may trigger hardfault
Background
The origin of this issue is our desire to eliminate the function of storing
"regs" in g_current_regs and instead utilize (*running_task)->xcp.regs for storage.
The benefits of this approach include faster storage speed and
avoiding multiple accesses to g_current_regs during context switching,
thus ensuring that whether returning from an interrupt or an exception,
we consistently use this_task()->xcp.regs
Issue Encountered
However, when storing registers, we must ensure that (running_task)->xcp.regs is invalid
so that it can be safely overwritten.
According to the existing logic, the only scenario where (running_task)->xcp.regs
is valid is during restore_context. We must accurately identify this scenario.
Initially, we used the condition (running_task)==NULL for this purpose, but we deemed
this approach unsatisfactory as it did not align well with the actual logic.
(running_task) should not be NULL. Consequently, we adopted other arch-specific methods for judgment,
but due to special logic in some arch, the judgment was not accurate, leading to this issue.
Solution:
For armv6-m, we haven't found a more suitable solution, so we are sticking with (*running_task)==NULL.
For armv7-m/armv8-m, by removing support for primask, we can achieve accurate judgment.
PRIMASK is a design in armv6-m, that's why arm introduce BASEPRI from armv7-m.
It's wrong to provide this option for armv7-m/armv8-m arch.

Convenient for qemu debugging and adding ci check
We can learn to use the following command to mount 9pfs on qemu64:
qemu-system-aarch64 -cpu max -nographic \
-machine virt,virtualization=on,gic-version=3,mte=on \
-fsdev local,security_model=none,id=fsdev0,path=/xxxx -device virtio-9p-device,id=fs0,fsdev=fsdev0,mount_tag=host \
-chardev stdio,id=con,mux=on, -serial chardev:con \

Add an option to use HSE on the Nucleo-H563ZI with board modification. This is enabled through board Kconfig.
It supplies the same PLL output frequencies using the HSE instead of HSI, for significantly more precise clocks.
