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 DRAM_BASE. config ARM_MPU bool 'Use the ARM v7 PMSA Compliant MPU' depends on CPU_V7 || CPU_V7M default y if CPU_V7 help Some ARM systems without an MMU have instead a Memory Protection Unit (MPU) that defines the type and permissions for regions of memory. If your CPU has an MPU then you should choose 'y' here unless you know that you do not want to use the MPU.
