S32C1I instructions may target cached, cache-bypass,

are not permitted to access memory addresses in data ROM,
instruction memory or the address region allocated to
the XLMI port. Attempts to direct the S32C1I at these
addresses will cause an exception.

Modify the kernel to use only atomic_xx and atomic64_xx interfaces,
avoiding the use of sizeof or typeof to determine the type of
atomic operations, thereby simplifying the kernel's atomic
interface operations.

In the source code of qemu or linux, there is a check for the virtio version
/* Check device version */
priv->version = readl(priv->base + VIRTIO_MMIO_VERSION);
if (priv->version < 1 || priv->version > 2) {
debug("(%s): version %d not supported!\n",
udev->name, priv->version);
return 0;
}
/* Check device ID */
uc_priv->device = readl(priv->base + VIRTIO_MMIO_DEVICE_ID);
if (uc_priv->device == 0) {
/*
* virtio-mmio device with an ID 0 is a (dummy) placeholder
* with no function. End probing now with no error reported.
*/
return 0;
}

Fix CMake-based build system to include the toolchain's libm only
when `CONFIG_LIBM_TOOLCHAIN` is selected. Before this commit, if
the user selected `CONFIG_LIBM_NEWLIB`, for instance, the build
system would still link the toolchain's libm functions instead of
the ones provided by newlib.
PS: this commit applies the same changes previously introduced for
the other architectures.
Source code under `newlib/newlib/newlib/libm/machine/$(ARCH)/*.c`
should be added before common source code from `../../common/*.c`.
Take `newlib/newlib/newlib/libm/machine/riscv/s_fma.c` as an
example:
```
double
fma (double x, double y, double z)
{
double result;
asm ("fmadd.d %0, %1, %2, %3" : "=f" (result) : "f" (x), "f" (y), "f" (z));
return result;
}
```
Note that the common `s_fma.c` will be included by the source file
directly. The order of adding the files to CSRCS matters here.
Although the CMake-based build system does not have the same build
problem of including the a source-file with the same in the wrong
order, this commit also changes the order of inclusion for CMake
too to keep it consistent.

reason:
up_set_current_regs initially had two functions:
1: To mark the entry into an interrupt state.
2: To record the context before an interrupt/exception. If we switch to
a new task, we need to store the upcoming context regs by calling up_set_current_regs(regs).
Currently, we record the context in other ways, so the second function is obsolete.
Therefore, we need to rename up_set_current_regs to better reflect its actual meaning,
which is solely to mark an interrupt.

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 \

-fsdev local,security_model=none,id=fsdev0,path=/xxxx -device virtio-9p-device,id=fs0,fsdev=fsdev0,mount_tag=host \

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.
The feature of preventing the same ID frame rotation should be done in the lowerhalf, not in the upperhalf.

Adding the STM32H5 FDCAN Hardware definitions. The register set is identical to the STM32G4. No major changes other than changing G4 to H5 and removing ifdef requirement for STM32G4.

EEFC read sequence requires read length in words instead of bytes,
therefore bytes given by the user has to be recalculated to words.
The calculation however had a mistake in brackets and was just adding
1 to buflen instead of recalculating it to 4 byte words. This caused
global array g_page_buffer to overflow for some reads.
This fixes the calculation.
