1c8e12406e compile/opt: add config DEBUG_LINK_MAP
Selecting this option will pass "-Map=$(TOPDIR)$(DELIM)nuttx.map" to ld
when linking NuttX ELF. That file can be useful for verifying
and debugging magic section games, and for seeing which
pieces of code get eliminated with DEBUG_OPT_UNUSED_SECTIONS.

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.

Arm v8-M Architecture Reference Manual:

C2.4.103 LE, LETP

B3.28 Low overhead loops:

An INVSTATE UsageFault is raised if a LE instruction is executed and FPSCR.LTPSIZE does not read as four.
When a new floating-point context is created and FPCCR.ASPEN is set to zero it is the responsibility of software
to correctly initialize FPSCR.LTPSIZE.

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
with clang and enable the optimization flag (-Ofast), up_getsp()
call will be earlier than push {r0-r9,lr}, the end address of color
stack will overlap with saved registers.

Compile line:
clang --target=arm-none-eabi -c "-Ofast" -fno-builtin -march=armv8.1-m.main+mve.fp+fp.dp \
-mtune=cortex-m55 -mthumb -mfpu=fpv5-d16 -mfloat-abi=hard -D__NuttX__ -common/arm_checkstack.c -o  arm_checkstack.o

d5ea259828 RISC-V: Combine 3 variables that depend on CPU amount into one
IRQ_NSTACKS, ARCH_CPU_COUNT, CONFIG_SMP_NCPUS all relate to each
other. However, a bit of clean up can be done and everything can
be merged into SMP_NCPUS.

The MPFS bootloader case works also as it requires only 1 IRQ stack
for the hart that executes as bootloader.
