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
23 depends on CPU_ARM740T || CPU_ARM946E || CPU_ARM940T
27 hex 'FLASH Size' if SET_MEM_PARAM
28 depends on CPU_ARM740T || CPU_ARM946E || CPU_ARM940T
32 hex 'Hard wire the processor ID'
34 depends on !(CPU_CP15 || CPU_V7M)
36 If processor has no CP15 register, this processor ID is
37 used instead of the auto-probing which utilizes the register.
39 config REMAP_VECTORS_TO_RAM
40 bool 'Install vectors to the beginning of RAM'
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.
47 If the region contains read-write memory, say 'n' here.
49 If your CPU provides a remap facility which allows the exception
50 vectors to be mapped to writable memory, say 'n' here.
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.
57 bool 'Use the ARM v7 PMSA Compliant MPU'
58 depends on CPU_V7 || CPU_V7M
61 Some ARM systems without an MMU have instead a Memory Protection
62 Unit (MPU) that defines the type and permissions for regions of
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.
