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. | ||
