+	  In nommu mode, the hardware exception vectors are normally
+	  placed at address 0x00000000. However, this region may be

+	  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.
