Some toolchains may define CLOCK_REALTIME and
CLOCK_MONOTONIC in their libc headers
with values that differ from Zephyr's internal
SYS_CLOCK_REALTIME and SYS_CLOCK_MONOTONIC.
To ensure consistent behavior across all boards and
toolchains, Introduce a helper function to map
CLOCK_REALTIME and CLOCK_MONOTONIC to Zephyr's internal
clock IDs (SYS_CLOCK_REALTIME and SYS_CLOCK_MONOTONIC).
This prevents mismatched clock IDs being passed to
the kernel, avoiding invalid clockid errors when using
functions like clock_gettime().

Fix for CID 529870, where Coverity found an issue where `timespec.tv_sec`
is never greater than `UINT64_MAX / NSEC_PER_SEC` (18446744073).
This is naturally true when `time_t` is only 32-bit, which is actually
never the case for any Zephyr platform aside from `native_sim/native/32`.
When `time_t` is a signed 64-bit value, at some point in the future, but
maybe not in our lifetimes, `timespec.tv_sec` could exceed 18446744073,
since `INT64_MAX > UINT64_MAX / NSEC_PER_SEC`.
We should not see coverity issues errors like this in the future, once we
have a consistent `time_t` representation across all Zephyr platforms.

Some of the locks are created in supervisor mode (i.e. stdout one),

the sum of free_bytes and allocated_bytes doesn't remain constant after
each allocation. This convention doesn't match glibc's behavior. This

Signed-off-by: Iuliana Prodan <iuliana.prodan@nxp.com>
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()).

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.

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.
