- 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
- default 0x00800000
- config DRAM_SIZE
- hex '(S)DRAM SIZE' if SET_MEM_PARAM
- default 0x00800000
- config FLASH_MEM_BASE
- hex 'FLASH Base Address' if SET_MEM_PARAM
- default 0x00400000
- config FLASH_SIZE
- hex 'FLASH Size' if SET_MEM_PARAM
- default 0x00400000
- 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'
- 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.
