initramfs boot issues with MPC8315

[Dave Glenton]

Hi,
 
 
I am having problems getting a NOR flash based PowerPC to boot. Up until
now I have been developing successfully using nfs and are now attempting
to boot the board from flash.
 
I initially tried using a ramdisk and the resulting rootfs file system
is larger than the 4MB Flash space I have available.
 
If I select initramfs as the target image I end up with a
initramfs.cpio.gz.uboot image of 1.4MB.
 
However when I transfer the kernel, rootfs and dtb to flash and boot the
system the kernel fails to find init. (See boot log below) I have read
that initramfs dose not require boot args, is this correct?
 
I have also tried booting with using bootm FE500000 - FE700000 with no
improvement
 
Any suggestions gratefully received

Dave
