Install vectors to the beginning of RAM


Linux Kernel Configuration
└─>Install vectors to the beginning of RAM
In linux kernel since version 2.6.17 (release Date: 2006-06-17)  
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.
