There are SoCs that have different memory maps for device and driver.
Therefore the shared memory between them has different values and we
need to convert the addresses.
This commit introduces address translation support for OpenAMP:
- implements the address translation functions;
- returns the I/O operations used for address translation.
The ops can be used in Libmetal (see metal_io_init()).

Coverity regularly raised a CID with every release that it found
`sizeof(char **)` confusing and somehow nonportable.
With every release, it needed to be marked as a false positive.
Change `sizeof(char **)` to `sizeof(void *)` to silence the
CID warnings.

Enhance flexibility by allowing vendors to define their own

Remove POSIX clock_gettime() from the common libc time implementation,
since POSIX should not be a dependency for ISO C.
Instead, use the newly added lib/os sys_clock API.
Specifically, sys_clock_gettime().
Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>
Additional entries for the sys_clock API, comprised of:
* sys_clock_gettime()
* sys_clock_settime()
* sys_clock_nanosleep()
along with the constants
* SYS_CLOCK_REALTIME
* SYS_CLOCK_MONOTONIC
* SYS_TIMER_ABSTIME
The primary motivation for this API is so that libc and other
libraries have a familiar-enough API to reach to when POSIX
is not available, since POSIX is optional in Zephyr.
By adding this API to lib/os, we also eliminate dependency cycles
between libc and posix, as lib/os is a mutual dependency.

in CI) when CONFIG_TIMEOUT_64BIT=n.

for information about the purpose of this change.
Modifies run actions of hierarchical state machines
to return a value indicating if the event was handled
by the run action or should be propagated up to the
parent run action. Flat state machines are not affected,
and their run action returns void.
smf_set_handled() has been removed and replaced by
this return value. smf_set_state() will not propagate
events regardless of the return value as the transition
is considered to have occurred.
Documentation, tests, samples, has been updated.
USB-C and hawkBit use SMF and have been updated to use
the new return codes.

Introduce a binary min-heap implementation as a generic data structure

It's possible for newlib/picolib libc libraries to
internally call sysconf() which would execute zephyr's
implementation. However, if the _SC* defines do not have
matching values, then the incorrect switch case executes.
This issue arises when using newlib/picolib libc that includes
sysconf implementation for ARM. With current defaults, the
zephyr sysconf() overrides the original libc sysconf() so
we must ensure proper operation.
We will switch to the #define list just like newlib/picolib.
We can't currently use their unistd.h directly due to a domino
of declaration conflicts.
For the "small" macro implementation, we have to drop using
CONCAT to prevent pre-expansion of the new #defines

Implement the POSIX_CLOCK_SELECTION Option Group.
This was mostly already done, but compiled / linked in the wrong places.
E.g. pthread_condattr_getclock() and pthread_condattr_setclock() were
in pthread.c and part of POSIX_THREADS_BASE. clock_nanosleep() was in
clock.c and part of POSIX_TIMERS.
This change builds them as part of clock_selection.c with

Move creation of last section id from ld linker script LONG() usage to
C code with last section attribute.
The use of `LONG()` works correctly with ld but lld emits a warning
because .last_section section is not allocated as there are no matching
input sections and discards the `LONG()` call, meaning the last section
identifier will not be present in the flash.
> ld.lld: warning: ignoring memory region assignment for
> non-allocatable section '.last_section'
Placing the last section id in `.last_section` in C code makes lld
allocate the memory for the id and thereby create the output section
with the correct output.
