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.

54config ARM_MPU

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