| 40 | The kernel needs to change the hardware exception vectors. |
| 41 | In nommu mode, the hardware exception vectors are normally |
| 42 | placed at address 0x00000000. However, this region may be |
| 43 | occupied by read-only memory depending on H/W design. |
| 44 | |
| 45 | If the region contains read-write memory, say 'n' here. |
| 46 | |
| 47 | If your CPU provides a remap facility which allows the exception |
| 48 | vectors to be mapped to writable memory, say 'n' here. |
| 49 | |
| 50 | Otherwise, say 'y' here. In this case, the kernel will require |
| 51 | external support to redirect the hardware exception vectors to |
| 52 | the writable versions located at DRAM_BASE. |
