7 bool "Set flash/sdram size and base addr"
9 Say Y to manually set the base addresses and sizes.
10 otherwise, the default values are assigned.
13 hex '(S)DRAM Base Address' if SET_MEM_PARAM
17 hex '(S)DRAM SIZE' if SET_MEM_PARAM
21 hex 'FLASH Base Address' if SET_MEM_PARAM
25 hex 'FLASH Size' if SET_MEM_PARAM
29 hex 'Hard wire the processor ID'
31 depends on !(CPU_CP15 || CPU_V7M)
33 If processor has no CP15 register, this processor ID is
34 used instead of the auto-probing which utilizes the register.
36 config REMAP_VECTORS_TO_RAM
37 bool 'Install vectors to the beginning of RAM'
39 The kernel needs to change the hardware exception vectors.
40 In nommu mode, the hardware exception vectors are normally
41 placed at address 0x00000000. However, this region may be
42 occupied by read-only memory depending on H/W design.
44 If the region contains read-write memory, say 'n' here.
46 If your CPU provides a remap facility which allows the exception
47 vectors to be mapped to writable memory, say 'n' here.
49 Otherwise, say 'y' here. In this case, the kernel will require
50 external support to redirect the hardware exception vectors to
51 the writable versions located at DRAM_BASE.
54 bool 'Use the ARM v7 PMSA Compliant MPU'
58 Some ARM systems without an MMU have instead a Memory Protection
59 Unit (MPU) that defines the type and permissions for regions of
62 If your CPU has an MPU then you should choose 'y' here unless you
63 know that you do not want to use the MPU.
