+         The kernel needs to change the hardware exception vectors.
+         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.
