However, this region may be 43 occupied by read-only memory depending on H/W design. 44 45 If the region contains read-write memory, say 'n' here. 46 47 If your CPU provides a remap facility which allows the exception 48 vectors to be mapped to writable memory, say 'n' here. 49 50 Otherwise, say 'y' here. In this case, the kernel will require 51 external support to redirect the hardware exception vectors to 52 the writable versions located at DRAM_BASE. 53 54 config ARM_MPU 55 bool 'Use the ARM v7 PMSA Compliant MPU' 56 depends on CPU_V7 57 default y 58 help 59 Some ARM systems without an MMU have instead a Memory Protection 60 Unit (MPU) that defines the type and permissions for regions of 61 memory. 62 63 If your CPU has an MPU then you should choose 'y' here unless you 64 know that you do not want to use the MPU.
