+config SET_MEM_PARAM
+ bool "Set flash/sdram size and base addr"
+ help
+ Say Y to manually set the base addresses and sizes.
+ otherwise, the default values are assigned.
+
+config DRAM_BASE
+ hex '(S)DRAM Base Address' if SET_MEM_PARAM

+config FLASH_SIZE

+config PROCESSOR_ID
+ hex 'Hard wire the processor ID'
+ default 0x00007700
+ depends on !(CPU_CP15 || CPU_V7M)
+ help
+ If processor has no CP15 register, this processor ID is
+ used instead of the auto-probing which utilizes the register.
+
+config REMAP_VECTORS_TO_RAM
+ bool 'Install vectors to the beginning of RAM' if DRAM_BASE
+ depends on DRAM_BASE
+ help
+ The kernel needs to change the hardware exception vectors.
+ In nommu mode, the hardware exception vectors are normally
+ placed at address 0x00000000. However, this region may be
+ occupied by read-only memory depending on H/W design.
+
+ If the region contains read-write memory, say 'n' here.
+
+ If your CPU provides a remap facility which allows the exception
+ vectors to be mapped to writable memory, say 'n' here.
+
+ Otherwise, say 'y' here. In this case, the kernel will require
+ external support to redirect the hardware exception vectors to
+ the writable versions located at DRAM_BASE.
+
+config ARM_MPU
+ bool 'Use the ARM v7 PMSA Compliant MPU'
+ depends on CPU_V7
+ default y
+ help
+ Some ARM systems without an MMU have instead a Memory Protection
+ Unit (MPU) that defines the type and permissions for regions of
+ memory.
+
+ If your CPU has an MPU then you should choose 'y' here unless you
+ know that you do not want to use the MPU.
