2026-08-26[arm][cortex-m4] Add hardware stack guard supporthanzhijian
Enable RT_USING_HW_STACK_GUARD on Cortex-M4, which was previously only available on Cortex-M7 and Cortex-M33. Core porting (libcpu/arm/cortex-m4/): - Add mpu.c/mpu.h/mputype.h aligned with the Cortex-M7 MPU layer. The only difference is the default memory type attribute: Cortex-M4 has no L1 cache, so the cacheability bits are reduced to three cases. - Add rt_hw_stack_guard_init() to cpuport.c. - Add missing #include <rtconfig.h> to context_gcc.S and invoke rt_hw_mpu_table_switch() in the PendSV context switch path. - Update SConscript to exclude mpu.c when memory protection is disabled. BSP reference (bsp/stm32/stm32f407-fk407m2-zgt6/): - board.h: include rtthread.h and define NUM_STATIC_REGIONS. - board.c: define static_regions[] marking the Flash region read-only, guarded by RT_USING_MEM_PROTECTION so it is not enabled by default.
2026-08-12fix(dm): route Cortex-M resets through power coreRbb666
2026-08-12feat(dm): support OFW on Cortex-M targetsRbb666
Add the ARM NVIC PIC driver, no-MMU I/O mapping, built-in FDT support, and Cortex-M CPU hooks required by the native RT-Thread device model.
