Rename MPU region attribute macros (REGION_RAM_ATTR → REGION_RW_NA_ATTR,
REGION_URAM_ATTR → REGION_RW_RW_ATTR) to explicitly indicate access permissions.
Add new REGION_RO_RO_ATTR and REGION_RO_NA_ATTR macros for read-only region definitions.

Change the default pthread mutex robustness from ROBUST to UNSAFE when
CONFIG_PTHREAD_MUTEX_BOTH is enabled. This reflects the practical default
and allows removal of tracking code for non-robust mutexes, improving
performance and reducing memory overhead.

This lock is currently used in three places,
mainly to protect tls->tl_mhead. Among them,
pthread_mutex_add and pthread_mutex_remove involve
writing to tls->tl_mhead, and there is
certainly no conflict within the same thread.
As for pthread_mutex_inconsistent, it involves reading. Currently,
it can only be called when the TCB task corresponding to
this tls exits, and the TCB corresponding to the
tls can no longer continue to run.
It seems that adding the lock serves no real purpose.

ARM specifies that SysTick RELOAD must be programmed with N-1 to get a period of N CPU cycles.
Adjust the timeout/reload conversions accordingly: subtract 1 when writing RELOAD and add 1 back when converting RELOAD to a timeout/interval.
Also clamp RELOAD to the valid 24-bit range (1..0x00ffffff) for Armv7-M/Armv8-M to avoid invalid values.

calls the ns_bound function.
And the advertisement message to remote core will generate many
the advertisement ack message from remote core, these advertisement
ack messages can't be processed at times by rptun thread.
This can cause rptun thread to block when the number of advertisement
message exceeds the number of ipc buffers between local core and

Add support for handling non-maskable interrupts (NMI) on TriCore
platforms. The NMI trap handler `tricore_nmitrap()` is provided as a weak
function that prints diagnostic information and invokes a panic with
register context. The main trap dispatcher will invoke `tricore_nmitrap`
when an NMI trap class is detected.
This change improves diagnostics when watchdog-induced NMIs or other
non-maskable exceptions occur during runtime.
