Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.
As long as the GNSS feature is not used, GNSS RAM can be used as general memory.
This memory is 640KByte total, which is lower performance than the application RAM.
It is possible to locate text, data and bss into GNSS RAM and to use as heap area.

Current implementation of QSPI in SPI mode was available only for MCUs
that do not have standard SPI at all. MCUs with both QSPI and SPI can
however also use QSPI in SPI mode and thus have one more SPI bus. This
commit adds required defines and config options to support QSPI in SPI
mode for all SAMv7 MCUs.

Port based on arch/arm/nrf53.
Modem not fully supported yet. At the moment, initialization and AT interface work.
Sockets and GNSS interface will be added later.
Basic work required for uniprocessor CortexR52 (ARMv8R AARCH32) using
GICv3 and CP15 mapped arch timer.
Tested on ARM FVP 11.20.
Port is based on ARMv8R AARCH64 and ARMv7R code. Excuse possible copy-paste leftovers.
Notify the compiler that the condition flag has changed to prevent the
compiler from optimizing and reordering instructions, which may cause exceptions.

arm-none-eabi-gcc 12.2.0 gives the following warnings:
error: 'primask' is used uninitialized
error: 'primask' may be used uninitialized
We use Werror and the file is indirectly included in different
places. I suggest telling the compiler to ignore these warnings
since primask is initialized on the first assembly line.
This is the only problem I encountered so far when upgrading the compiler.
The function is not relevant any longer, remove it. Also remove
save_addrenv_t, the parameter taken by up_addrenv_restore.
Implement addrenv_select() / addrenv_restore() to handle the temporary
instantiation of address environments, e.g. when a process is being
created.
Detach the address environment handling from the group structure to the
tcb. This is preparation to fix rare cases where the system (MMU) is left
without a valid page directory, e.g. when a process exits.
This is preparation for moving address environments out of the group
structure into the tcb.
Why move ? Because the group is destroyed very early in the exit phase,
but the MMU mappings are needed until the context switch to the next
process is complete. Otherwise the MMU will lose its mappings and the
system will crash.
The dependency should be vice versa; the MM_SHM should depend on the
existence of the virtual memory range allocator.
Create a new CONFIG flag CONFIG_ARCH_VMA_MAPPING, which will define that
there is a virtual memory range allocator. Make MM_SHM select that flag
