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? FWIW, that would also let us do: config XIP_KERNEL bool "Kernel Execute-In-Place from ROM" depends on PHYS_OFFSET_0 || PHYS_OFFSET_1 || PHYS_OFFSET_2 || PHYS_OFFSET_3 || PHYS_OFFSET_7 || PHYS_OFFSET_8 || PHYS_OFFSET_A || PHYS_OFFSET_C We can probably come up with a more elaborate way to prevent configurations that have more than one of these set.
