9     Say Y to manually set the base addresses and sizes.
10     otherwise, the default values are assigned.

33      If processor has no CP15 register, this processor ID is
34      used instead of the auto-probing which utilizes the register.

36config REMAP_VECTORS_TO_RAM

38    depends on DRAM_BASE
39    help
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.
