#define PMP_SOC_REGION_DEFINE	(		name,

Value:

        static const STRUCT_SECTION_ITERABLE(pmp_soc_region, name) = {                             \
                .start = (const void *)(_start),                                                   \
                .end = (const void *)(_end),                                                       \
                .perm = (_perm),                                                                   \
        }

Define a SoC-specific PMP region.

This macro allows SoCs to register memory regions that require PMP protection. The regions are collected at link time and programmed during PMP initialization.

Parameters

name	Unique identifier for this region
_start	Start address of the region (pointer or linker symbol)
_end	End address of the region (pointer or linker symbol, exclusive)
_perm	PMP permission flags (PMP_R | PMP_W | PMP_X)
