32 The kernel needs to change the hardware exception vectors.
33 In nommu mode, the hardware exception vectors are normally
34 placed at address 0x00000000. 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.
