NUM_MEM_REGIONS / NUM_CONFIGURABLE_REGIONS / NUM_EXCLUSIVE_REGIONS had no Kconfig defaults. Enabling RT_USING_HW_STACK_GUARD without explicitly setting them generated empty macros in rtconfig.h (e.g. '#define NUM_CONFIGURABLE_REGIONS'), which expanded into invalid C expressions like '(2 + )' and 'for (i = 0U; i < ; i++)', breaking compilation for cortex-m4/m7/m33 MPU code. Add safe defaults: NUM_MEM_REGIONS=8, NUM_CONFIGURABLE_REGIONS=0, NUM_EXCLUSIVE_REGIONS=0. Also document the MemManage_Handler strong-symbol conflict with CubeMX-generated stm32f4xx_it.c and how to resolve it. Reported-by: wdfk-prog

|
The number of MPU regions supported by the target MCU. The common value
|
|
for Cortex-M4/M7/M33 is 8, but some MCUs expose 4, 12, or 16 regions.
|
|
Set this to the actual value reported by the hardware, otherwise the MPU
|
|
initialization will reject the configuration at runtime.
