In preparation for introducing a warning.
Unquoted string defaults work through a quirk of Kconfig (undefined
symbols get their name as their string value), but look confusing. It's
done inconsistently now too.

Previously, there was no easy command-line solution for loading
a Zephyr program to (internal) flash.
So, the default development method was to load via gdb/openocd
to SRAM and debug from there, thus making the cc3220sf platform
non-XIP (CONFIG_XIP=n) by default.
With new openocd v 1.10 updates from TI (git.ti.com/sdo-emu),
the image can now be flashed and debugged via gdb/openocd,
so the default will be changed to XIP (CONFIG_XIP=y).

LPUART (Low-power UART) peripheral is just like ordinary U(S)ART
which lives in a separate clock/power domain.
Therefore already existing code could be reused as is
almost entirely.

STM32Lx LPUART peripherals do not fit well into existing U(S)ART
port numbering scheme, so there will be two separate namespaces
in Kconfig: one for U(S)ARTs and one for LPUARTs.

The metairq feature exposed the fact that all of our arch code (and a
few mistaken spots in the scheduler too) was trying to interpret
"preemptible" threads independently.
As of the scheduler rewrite, that logic is entirely within sched.c and
doing it externally is redundant. And now that "cooperative" threads
can be preempted, it's wrong and produces test failures when used with
metairq threads.

The PPB, Peripheral, and any other I/O regions have been
removed, the Shareable options are only important with
unlocked dual cores. Just use the background mapping,
which is RWX for supervisor and no access for user mode.
The flash region needs to be kept to indicate read-only
policy. The RAM regions need to be kept to disable execution.

The STM32L432 SoC has a standard non-OTG USB controller. Add an entry
for it in stm32l432.dtsi and add the corresponding DTS fixup entries.

USB OTG is currently enable for the whole STM32L4 family, while only a
few of them actually support it:
- STM32L475, STM32L476 and STM32L496 have an OTG controller
- STM32L432, STM32L433 and STM32L452 have an USB controller
- STM32L431, STM32L451 and STM32L471 do not have any USB controller
Fix that by moving the DT entry from stm32l4.dtsi to stm32l475.dtsi
and by adding a #ifdef #endif around the corresponding DTS fixup
entries.

Some code was developped around MPU support in ealy stage
of feature introduction. This code was gated under MPU_ENABLE
flag which does not exist and hence code has never been
enabled nor tested.
Since there has been futher MPU development since then, it seems
safer to simply remove that code and associated Kconfig symbols
to avoid that someone starts using it while it was not part of
MPU development track.

The initial user stack pointer gets rounded to STACK_ALIGN_SIZE,
which can be much finer granularity than MPU regions. With
certain stack size values passed to k_thread_create(), the stack
pointer can be set past the defined region for the user thread's
stack, causing an immediate MPU fault.

Upon return from a syscall handlers, the r1, r2, and r3 registers
could contain random kernel data that should not be leaked to user
mode. Zero these out before returning from _arm_do_syscall().
Fixes#7753.
The invocation macros need a clobber if r1, r2, or r3 are not used
to carry syscall arguments. This is a partial fix for #7754 but
there appear to be other issues.

Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the arch files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.
In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.
