dc961baaea 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

370152f3ba RISC-V: Move mhartid to own assembly macro+function
Hartid and cpuindex are not the same thing. Hartid is needed regardless
of SMP, for external interrupt handling etc.

SMP needs cpuindex which might not be index == hartid, so both are
needed. IMO it is clearer to provide separate API for both.

Currently the implementation of up_cpu_index is done a bit lazily,
because it assumes hartid == cpu index, but this is not 100% accurate,
so it is still missing some logic.

ff210e1c2d arch/stack_color: correct the end address of stack color
The different optimization of compilers will cause ambiguity in
obtaining sp through up_getsp() in arm_stack_color(), if compile

call will be earlier than push {r0-r9,lr}, the end address of color
stack will overlap with saved registers.

71ced1f1a9 RISC-V: Implement skeleton for a per CPU structure
It might be useful to store things in memory per CPU. The tricky part
is that all CPUs run the same code and see the same memory, so some
kind of centralized access is required.

For now, the structure contains the hart id.

Access to the structure elements is provided via sscratch, which is
unique for every hart!

c15b6701ce RISC-V: Implement option to run NuttX in supervisor mode (S-mode)
- Add config "ARCH_USE_S_MODE" which controls whether the kernel
  runs in M-mode or S-mode
- Add more MSTATUS and most of the SSTATUS register definitions
- Add more MIP flags for interrupt delegation
- Add handling of interrupts from S-mode
- Add handling of FPU from S-mode
- Add new context handling functions that are not dependent on the trap
  handlers / ecall

NOTE: S-mode requires a companion SW (SBI) which is not yet implemented,
      thus S-mode is not usable as is, yet.

35009c5d4d sim: Fix init of static C++ constructors when using glibc >= 2.34
glibc 2.34 changed the dynamic linker behavior during the startup
process, which makes the previous "__init_array_start" replacement trick
non-effective.
Now the dynamic linker parses the constructors/destructors information
from the DYNAMIC segment of the program.

e6d6734db2 ARCH_ADDRENV: Add guard against mis-configuration
When process a is switched to process b, the address environment is
swapped with a call to group_addrenv(). The stack upon entry will be
a's, and upon exit b's. This will fail, so a neutral stack is required,
either a kernel stack or an IRQ stack.

Infrastructure for an IRQ stack is already in place, so give a hint
that an interrupt stack should be provided if address environments
are enabled.

4456b13c19 riscv/bl602: Remove check for LCD driver
## Summary

`bl602_spi_cmddata()` implements SPI Cmd/Data `SPI_CMDDATA()` for only 3 LCD drivers: ST7735, ST7789 and GC9A01.

This patch removes the check for LCD drivers, so that SPI Cmd/Data will work for all LCD drivers.

More details: https://github.com/apache/incubator-nuttx/pull/5898

## Impact

This change impacts LCD drivers that call `SPI_CMDDATA()`.

Previously `SPI_CMDDATA()` would fail with `ENODEV` for LCD drivers other than ST7735, ST7789 and GC9A01.

After patching, `SPI_CMDDATA()` will work correctly with all LCD drivers.

## Testing

We tested with LVGL and ST7789 on PineCone BL602:

-   [Testing with LVGL](https://github.com/lupyuen/st7789-nuttx#run-lvgl-demo)

As for regular SPI Devices that don't require SPI Cmd/Data, we tested `CONFIG_SPI_CMDDATA=y` with Semtech SX1262 SPI Transceiver on PineCone BL602:

a98a599cb9 arm/cortex-[a|r]: IRQ Switch return should with shadow SPSR
The SPSR is used to store the current value of the CPSR when an exception
is taken so that it can be restored after handling the exception.
Each exception handling mode can access its own SPSR.

User mode and System mode do not have an SPSR because they are not
exception handling modes.
