Is it really not possible to use maths in linker scripts? How have I never noticed that... Anyway, given that things only differ in the most significant nibble of the RAM base address I think something like this might work: /* NB: find out if one of these is already available somewhere */ #define __stringify(x) #x #define stringify(x) __stringify(x) #define SDRAM_OFFSET(x) 0x2##x /* or 0x4 */ #define CONFIG_SYS_SDRAM_BASE SDRAM_OFFSET(0000000) #define MEM_LAYOUT_ENV_SETTINGS \ "kernel_addr_r=" stringify(SDRAM_OFFSET(200000)) "\0" ...
