I currently have a linux ramdisk image (zImage.initrd.elf) stored in
linear flash. I also have a bit file with the xilinx EDK generated
bootloader in platform flash on an ML403. Is it neccessary to have
uboot with the linux kernel to be able to boot automatically or can i
simply alter the xilinx bootloader (if needed at all? )
Thanks,
Sam

U-Boot in not necessary. You can modify the xilinx bootloader to load
an elf file into ram and jump into it. When you migrate to using
arch/powerpc, you can use the simpleImage target which can be loaded
anywhere into ram before jumping to it.
Cheers,
