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 || CPU_V7M
default y if CPU_V7
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.
