It looks like usage of CONFIG_FLASH_{MEM_BASE,SIZE} is limited with:
arch/arm/mm/proc-arm740.S
arch/arm/mm/proc-arm940.S
arch/arm/mm/proc-arm946.S
So it might look confusing to see the option for anything except these.

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 depends on CPU_ARM740T || CPU_ARM946E || CPU_ARM940T default 0x00400000
config FLASH_SIZE hex 'FLASH Size' if SET_MEM_PARAM depends on CPU_ARM740T || CPU_ARM946E || CPU_ARM940T 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.
