3193aa3c97 arch: risc-v: Add MMU support for qemu-rv 
Summary:
- This commit adds MMU support for qemu-rv
- Please note that mtimer is disabled for S-mode because
  the mtimer needs to be accessed in M-mode

Impact:
- qemu-rv only

Testing:
- Tested with rv-virt:knsh64 (will be pushed later)

77e36d1acc risc-v/mpfs: introduce IHC driver 
This provides an example of Asymmetric Multiprocessing (AMP). The
master from Linux sends pings that this NuttX echoes back. The system
uses RPMsg from OpenAMP.

The Inter-Hart Communication module is present in the vendor's software
stack with the tag "2021.11". The software is present on github at the
polarfire-soc project. The following conditions must be met:

 1. FPGA programmed with 2021.11 software
 2. HSS (Vendor bootloader) with 2021.11 software
 3. U-boot and Linux kernel from 2011.11 software

Currently the IHC works as a slave only on the hart number 4.

On the NuttX side, this patch uses rptun that incorporates rpmsg and
virtio. If it used only rpmsg and virtio, the future maintenance would
likely be much heavier. Using rptun also simplifies many things.

Upon success, the master side from Linux may issue an example test:

root@icicle-kit-es-amp:/opt/microchip/amp/rpmsg-pingpong# ./rpmsg-pingpong

However, the rpmsg-pingpong.c (compiled on target with gcc), may need to
be modified as seen below to match the device id:
 - char *rpmsg_dev="virtio0.rpmsg-amp-demo-channel.-1.0";
 + char *rpmsg_dev="virtio0.rpmsg-amp-demo-channel.-1.1024";

This work uses a separate linker script. Due to a bug yet unknown to date,
a small NuttX, when loaded by the vendor HSS bootloader, will cause the
Linux kernel to hang at boot. Thus, the binary size is increased with
a section 'filler_area' whose only purpose is to increase the image size
so that the Linux kernel will boot up.

_xtensa_sig_trampoline is returned to after a context switch and not called
by the usual Window call instructions (call4, call8 and call12),
thus does not need the entry instruction.  Furthermore, the ENTRY instruction
in this case is messing up the backtrace as it creates an extra frame.

248b738f25 arm_addrenv: Add stubs for modifying permissions 
Adds stubs for up_addrenv_text_enable/disable_write. These don't have
to do anything as the ARM MMU allows setting access per mode. Currently
the settings for user .text area grants the kernel write access, but
revokes user write access.

9af8b740e6 Elf loader: give temporary write access to user .text memory 
When the .elf file is loaded from disk, the kernel must be given write
access to the allocated .text section in the task's address environment.

The access is removed after the elf is loaded and relocations are done.

NOTE:
The reason this works for the ARM implementation, is that the ARM MMU
can be configured to give write access for the privileged mode, but
revoke write access for the user mode.

Regardless, it would be smart to revoke write access even for the
kernel, when the kernel does not need it. This framework allows doing
that, if someone wishes to take up the task.

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

- Actually, QEMU supports sifive_u (not K210) but it works
  if FPU is disabled.
- This commit fixes this issue.

Impact:
- K210 with QEMU only

- 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.

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.
