S32C1I instructions may target cached, cache-bypass,
and data RAM memory locations. S32C1I instructions
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.

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.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

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Currently, we record the context in other ways, so the second function is obsolete.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.

reason:
1: spin_lock_init and spin_initialize have similar functionalities.
2: spin_lock and spin_unlock should be called in matching pairs.

reason:
When entering an exception or interrupt, there are two sets of registers:
one is the "running regs", which we need to save,
and the other is the "ready to running regs", which we may soon use.
For consistency in logic, we can always store the "running regs" in the regs field of g_running_tasks,
otherwise it may lead to errors in the storage location of the "running regs."
When we need to access the "running regs," we should uniformly retrieve them from the regs field of g_running_tasks.
As the next step, we will rename the set_current_regs/up_current_regs functions
for each architecture to more appropriate names, solely for the purpose of identifying interrupts.

In https://github.com/apache/nuttx/pull/13044,
LIBC_ARCH_ATOMIC was finally removed.
Howerver, the following chips still have the config.
- ARCH_CHIP_ESP32S3
- ARCH_CHIP_ESP32C3_GENERIC
- ARCH_CHIP_ESP32H2
This commit fixes the issue.
This patch fixed userspace headers conflict. Architecture-related definition and API should not be exposed to users.

If device encryption is not enabled by eFuse, and partiton mark as
encrypted flag, then encrypted MTD is used.
That is no problem in write and read operation, but failed while
using spi_flash_mmap(...) since de-encrypt is not processed.
So, back to use non-encrypted MTD following API Guide:
If flash encryption is not enabled, the flag "encrypted" has no effect
To make it easier to keep the linker scripts updated for both
MCUboot and "simple-boot", this commit merges them into a single
linker script with macros to enable/disable specific sections.
that pr requires chip turn on CONFIG_DRIVERS_BLUETOOTH to use bluetooth,
but not all defconig enable this option, so let's map bt_driver_register
to bt_netdev_register in header file in this case, and revert the unnessary
change in the related chip and board folders.
