b3baf95835 UMM: Implement getter for address environment heap start vaddr 
Using the Kconfig macro does not work for RISC-V target, as there the
user heap follows .data/.bss and does not obey any Kconfig provided
boundary.

Added stubs for ARM and Z80 also.

1322f82802 RISC-V: Copy kernel memory mappings to userspace addrenv 
Copy the kernel mappings to the new (user) address environment. The
copyuing is done exactly once. This relies on the fact that the kernel
L1/L2 mappings will never change, as all of the kernel memory is mapped
upon boot.

57127b9429 RISC-V: Initial support for CONFIG_BUILD_KERNEL 
This implements initial support for kernel build (address environments,
page allocator) for RISC-V.

This is done a bit differently compared to the ARMV7 implementation:

- Support implemented for Sv39 MMU, however the implementation should be
  extensible for other MMU types also.
- Instead of preserving and moving the L1 references around, a canonical
  approach is used instead, where the page table base address register
  is switched upon context switch.
- To preserve a bit of memory, only a single L1/L2 table is supported,
  this gives access to 1GiB of virtual memory for each process, which
  should be more than enough.

Some things worth noting:
- Assumes page pool is mapped with vaddr=paddr mappings
- The CONFIG_ARCH_XXXX_VBASE and CONFIG_ARCH_XXXX_NPAGES values are
  ignored, with the exception of CONFIG_ARCH_DATA_VBASE which is used
  for ARCH_DATA_RESERVE
- ARCH_DATA_RESERVE is placed at the beginning of the userspace task's
  address environment

Summary:
- I noticed that maix-bit:smp does not work with QEMU.
- Actually, QEMU supports sifive_u (not K210) but it works
  if FPU is disabled.
- This commit fixes this issue.

Impact:
- K210 with QEMU only

Testing:
- Tested with qemu-5.2

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.

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

c6942b68d5 arch/risc-v: Add handler for misaligned load/store 
Some risc-v based chips don't support unaligned data access,
it will trigger a exception and then lead to crash.

In this patch, we handle the misaligned access by software to make
system run continue.

with other risc-v based chips, in this patch, we keep the exception

- Access to PLIC via S-mode registers
- Access to IRQs via S-mode registers / definitions
- Initialize S-mode registers upon boot
- Initialize per CPU area before nx_start

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

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

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.
