| 31 | help |
| 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. |
