* ARMv8-M: Add SMP support to CM33 NTZ non-MPU port * Enable SMP for Arm Cortex-M33 NTZ port for GCC, ArmClang, and IAR toolchains. * Add per-core scheduler/port state: critical nesting. * Introduce spinlocks and inter-core yield/wakeup (SEV/WFE) plus primary/secondary core bring-up sync. * Update PendSV (i.e., context switch assembly) for core-safe preemption and restore paths. * Extend port macros/hooks for SMP in portmacrocommon.h, single-core builds remain unchanged. * Add the SMP boot sequence along with the necessary steps to enable SMP on Armv8-M based ports. This should help developers understand the requirements and process for enabling SMP on their Armv8-M based applications. * Update the kernel checker script to accept comma separated years in the copyright header. Signed-off-by: Ahmed Ismail <Ahmed.Ismail@arm.com> * Armv8-M: Copy SMP changes to all Armv8-M based ports This commit executes the `copy_files.py` python script to copy the changes applied in the previous commit (i.e., SMP changes) to all the Armv8-M based ports.

This directory tree contains the master copy of the FreeRTOS Armv8-M and Armv8.1-M ports. Do not use the files located here! These file are copied into separate FreeRTOS/Source/portable/[compiler]/ARM_[CM23|CM33|CM52|CM55|CM85|STAR_MC3]_NNN directories prior to each FreeRTOS release. If your Armv8-M and Armv8.1-M application uses TrustZone then use the files from the FreeRTOS/Source/portable/[compiler]/ARM_[CM23|CM33|CM52|CM55|CM85|STAR_MC3] directories. If your Armv8-M and Armv8.1-M application does not use TrustZone then use the files from the FreeRTOS/Source/portable/[compiler]/ARM_[CM23|CM33|CM52|CM55|CM85|STAR_MC3]_NTZ directories.
