pmp_soc_region Struct Reference

SoC-specific PMP region descriptor. More...

#include <pmp.h>

Data Fields
const void *	start
	Start address of the region (must be aligned to PMP granularity)
const void *	end
	End address of the region (exclusive)
uint8_t	perm
	PMP permission flags (PMP_R, PMP_W, PMP_X combinations)

Detailed Description

SoC-specific PMP region descriptor.

SoCs can define additional memory regions that need PMP protection using the PMP_SOC_REGION_DEFINE macro. These regions are automatically collected via iterable sections and programmed into the PMP during initialization.

Note: Uses start/end pointers instead of start/size to support regions defined by linker symbols where the size is not a compile-time constant.
