This patch adds new chip family, stm32wl5x. This is bare minimum
implementation of said chip. I've tested this by running nsh.
There are only two chips in this family, stm32wl55 and stm32wl54.
The only difference between them is that stm32wl55 has LORA.
stm32wl5 is dual CPU (not core!). Right now only CPU1 is implemented.
CPU0 has access to radio hardware (while CPU1 does not). Chip is
designed so that CPU0 handles radio traffic while CPU1 does the
heavy lifting with data - there is communication pipe between two
CPUs.
I plan to use nuttx on CPU1 and LORA from stm32cube on CPU0 so I
don't have implementing CPU0 right now - once we have working LORA
in nuttx this may change.
Peripherals (except for radio) are shared so it's best to focus on
CPU1 to initialize all peripherals so that CPU0 can only use them
later. There is no real benefit to implement CPU0 if we don't have
working LORA/radio support in nuttx.
In time I will be implementing more and more things from this chip.
Right now I would like this minimal implementation to be merged in
case someone wants to work on this chip as well.

patch v1->v2
- fixed formatting (suggested by Alan Carvalho de Assis)
- rebased patch to master (previous patch was based on nuttx-10.2
and did not compile on master)
since it is broken and inefficient, and then removed by:

arm/armv7-[a|r]: move fpu save/restore to assembly handler
Save/Restore FPU registers in C environment is dangerous practive,
which cannot guarantee the compiler won't generate the assembly code
with float point registers, especially in interrupt handling

After check the official specification of ARM ISA
and Thumb ISA, the arch_setjmp_thumb.S are written
by arm unified assembly language,
so it easy to make it works for ARM and thumb ISA.

Architecture support for STMicroelectronics STMU585xx MCUs. This is
based on corresponding code for STM32L5, but has been considerably
adjusted. Tested with a B-U585I-IOT02A board and a simple NSH
configuration, but only running NuttX in the non-secure world with
TrustedFirmware-M.

When NuttX is booted from a foreign (non NuttX)
bootloader. There as a possibility that the
bootloader configured the MPU, in an
incompatible way for the NuttX memory usage.
The option to reset the MPU before it is initialized
may not succeed if the bss and data initialization
code violated the previous MPU configurations.
Added herein are ARM_MPU_RESET and
ARM_MPU_EARLY_RESET. The former can be used
If the system is capable of booting and running
NuttX MPU configuration code without an MPU
violation. The latter is used if the system can
not run the bss and data initialization code.
These are options so that a NuttX may be configured to
not clobber a bootloader MPU configuration in a system
that is architected to share the MPU configuration task.
Summary:
- I noticed that make savedefconfig shows warnings regarding
'unmet direct dependencies (ARCH_HAVE_MODULE_TEXT)'
- This commit fixes this issue
Impact:
- None
Testing:
- Tested with spresense:wifi
