That is good, but the atix.rom will be compiled into normal image and fallback image.
Also for Fallback image, you will make linuxbios_ram.rom too big. finally image could be greater than 128K for four way and 8 way system. Maybe we can think about one way to let fallback image use the atix.rom in normal image. then the problem comes again: some time we need flash normal image only and keep fallback image for safe, So You need to make sure atix.rom in the exact same position.
