I made that work now and can prepare a patch. I had to drop "depends on !ARCH_MULTIPLATFORM" from XIP_KERNEL. That's because my machine only works with XIP_KERNEL as it only has 4 MiB of RAM. Also note that for !MMU you need to specify the base address and size of your RAM (DRAM_BASE, DRAM_SIZE) and flash (FLASH_MEM_BASE, FLASH_SIZE). So the resulting image is hardly runnable on different machines. (I don't know off-hand why these are needed though, maybe this can be discussed away.) So ARCH_MULTIPLATFORM is only good as it allows to simplify a few things, but the result isn't really multi-platform.
