However, this region may be 35 occupied by read-only memory depending on H/W design. 36 37 If the region contains read-write memory, say 'n' here. 38 39 If your CPU provides a remap facility which allows the exception 40 vectors to be mapped to writable memory, say 'n' here. 41 42 Otherwise, say 'y' here. In this case, the kernel will require 43 external support to redirect the hardware exception vectors to 44 the writable versions located at DRAM_BASE. 45
