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
	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 begining 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.
