Is there a way to provide a default for defaults?

We could have something like

config PHYS_OFFSET_0
	bool

config PHYS_OFFSET_1
	bool

config PHYS_OFFSET_2
	bool

... (we need 8 of the 16 possible addresses)


config PHYS_OFFSET
	hex "Physical address of main memory" if MMU
	default DRAM_BASE if !MMU
	default 0x00000000 if PHYS_OFFSET_0
	default 0x10000000 if PHYS_OFFSET_1
	default 0x20000000 if PHYS_OFFSET_2
	default 0x30000000 if PHYS_OFFSET_3
	default 0x70000000 if PHYS_OFFSET_7
	default 0x80000000 if PHYS_OFFSET_8
	default 0xa0000000 if PHYS_OFFSET_A
	default 0xc0000000 if PHYS_OFFSET_C


and then select one of the bool symbols from each platform.
Would that address your question?

Yes, but the ugliness factor isn't worth it IMHO.

I was wondering if something like this was possible:

config PHYS_OFFSET
        hex "Physical address of main memory" if MMU
        default DRAM_BASE if !MMU
        default 0x10000000 if FOO
        default 0x20000000 if BAR
        default 0x30000000 if BAZ
        default 0x00000000
