8 bool "Set flash/sdram size and base addr"
10 Say Y to manually set the base addresses and sizes.
11 otherwise, the default values are assigned.
14 hex '(S)DRAM Base Address' if SET_MEM_PARAM
18 hex '(S)DRAM SIZE' if SET_MEM_PARAM
22 hex 'FLASH Base Address' if SET_MEM_PARAM
26 hex 'FLASH Size' if SET_MEM_PARAM
30 hex 'Hard wire the processor ID'
32 depends on !(CPU_CP15 || CPU_V7M)
34 If processor has no CP15 register, this processor ID is
35 used instead of the auto-probing which utilizes the register.
37 config REMAP_VECTORS_TO_RAM
38 bool 'Install vectors to the beginning of RAM'
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.
45 If the region contains read-write memory, say 'n' here.
47 If your CPU provides a remap facility which allows the exception
48 vectors to be mapped to writable memory, say 'n' here.
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.
55 bool 'Use the ARM v7 PMSA Compliant MPU'
56 depends on CPU_V7 || CPU_V7M
59 Some ARM systems without an MMU have instead a Memory Protection
60 Unit (MPU) that defines the type and permissions for regions of
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.
