  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.
