37	  used instead of the auto-probing which utilizes the register.

39config REMAP_VECTORS_TO_RAM
40	bool 'Install vectors to the beginning of RAM'
41	help
42	  The kernel needs to change the hardware exception vectors.
43	  In nommu mode, the hardware exception vectors are normally
44	  placed at address 0x00000000. However, this region may be
45	  occupied by read-only memory depending on H/W design.
46
47	  If the region contains read-write memory, say 'n' here.
48
49	  If your CPU provides a remap facility which allows the exception
50	  vectors to be mapped to writable memory, say 'n' here.
51
52	  Otherwise, say 'y' here.  In this case, the kernel will require
53	  external support to redirect the hardware exception vectors to
54	  the writable versions located at DRAM_BASE.

56config ARM_MPU

60       help
61         Some ARM systems without an MMU have instead a Memory Protection
62         Unit (MPU) that defines the type and permissions for regions of
63         memory.
64
65         If your CPU has an MPU then you should choose 'y' here unless you
66         know that you do not want to use the MPU.
