This patch add support to use buttons example on raspberrypi-pico.
Note: unfortunately the raspberry-pico board doesn't have usables
buttons, then you need to add external buttons connected to GPIO16
and GPIO17.

As __start must be placed at a precise location, a separate, explicit
input section is needed to guarantee this.
Why is this an issue ? NuttX uses --entry=__start which puts __start in
its correct location, but out-of-tree builds won't work, so it more robust
to use an explicit section for the startup code and enforce its placement
in the linker script.

The video_controls.h is a public header file, and it is used by
videoio.h. So it should be moved to the include/sys directory.

In SMP mode, up_cpu_index()/this_cpu() are the same, both return the index of the physical core.
In AMP mode, up_cpu_index() will return the index of the physical core, and this_cpu() will always return 0

If a context switch occurs in syscall, the g_running_task need to be recorded for assert logic.
This copies the logic from arm platforms

When entering the function from an external bootloader, the CPU could be using PSP. But the following
code expects MSP to be in use.

We shouldn't panic the kernel when a user task excepts, we can just kill the user task and
it's children. Do this by returning to _exit() in kernel context.

Adds board definition for imx93-evk board
- Support for the Cortex-A55 core in i.MX93, support for the Cortex-M33
core is _not_ provided
- "nsh" profile is provided, this includes a minimalistic feature set
which boots the SoM to nsh console
- A bootloader is required, u-boot has been tested
Adds support for NXP i.MX9-series System-on-Module chips.
- Support for i.MX93 is added
- CPU is Cortex A55 / ARMv8.2A
- The chip also contains a Cortex M33, but no support is provided
- Supported drivers include lpuart only for now
This commit implements functions icjx_multireadpin and icjx_multiwritepin.
These functions can be used for multiple pin access (read/write) if
CONFIG_IOEXPANDER_MULTIPIN is selected. This access is generally
faster than one by one pin and may simplify user application.
Changes to general functions icjx_read and icjx_write were also required
to provide support for multiple data send/receive.

This driver is based on ESP32 TWAI CAN drivers currently available
in Nuttx, and captures the differences currently present across the
TWAI drivers for easy future adaption to remaining ESP32 platforms
with no loss of support/function. Also provides a generic SJA1000 CAN
driver solution that is CPU-architecture independent.
Changes:
- Low-level driver re-written to allow usage independent of CPU
architecture, and support both SJA1000 and TWAI CAN controllers.
- Platform-specific settings abstracted away to be provided by board
layer.
- Support for multiple instances of SJA1000 driver.
function bloaty() Add -D CMAKE_INSTALL_PREFIX="${NUTTXTOOLS}"/bloaty.
Improves workflow execution time because it is now cached.
Changed reference file to calculate the hash for key of actions/cache@v4. Now it is darwin.sh.
The overhead of spinlok is less than mutext (mutex need to call
enter_critical section.)
After this patch, `down_write_trylock` and `down_read_trylock` can be
use in interrupt context.
The instruction is protected with mutex only one instruction so using
spinlock is better.

We can decide whether use trustzone
After this patch, we can support the following mode:

Without Security Extensions n n n n
CHIP have NO trustzone
With Security Extensions y y n n
Only one bin in sec mode
With Security Extensions y n y n
TEE bin in sec mode
With Security Extensions y n n y
REE bin in non-sec mode

Purpose: make the the os crash when busyloop with interrupt disable
Follow the arm gicv2 spec, if we want to use the IRQ and FIQ
simultaneously when not using the processor Security Externsions.
We should:
1. IRQ to Group 1 and FIQ to Group 0;
2. Set CICC_CTLR.FIQEn to 1;
Then in NuttX:
1. implement the arm_decodefiq and directly crash in it;
2. provide interface to change the IRQ to FIQ, e.g. change the
watchdog IRQ to FIQ, so the watchdog can trigger even with the
interrupt disabled (up_irq_save() called);
