In nommu mode, the hardware exception vectors are normally placed at address 0x00000000. However, this region may be occupied by read-only memory depending on H/W design. If the region contains read-write memory, say 'n' here. If your CPU provides a remap facility which allows the exception vectors to be mapped to writable memory, say 'n' here. Otherwise, say 'y' here. In this case, the kernel will require external support to redirect the hardware exception vectors to the writable versions located at [31mCONFIG_DRAM_BASE[0m. config [31mCONFIG_ARM_MPU[0m bool 'Use the [31mCONFIG_ARM[0m v7 PMSA Compliant [31mCONFIG_MPU[0m' depends on [31mCONFIG_CPU_V7[0m default y help Some [31mCONFIG_ARM[0m systems without an [31mCONFIG_MMU[0m have instead a Memory Protection Unit ([31mCONFIG_MPU[0m) that defines the type and permissions for regions of memory.
