I'm working on the 2.6 kernel for MicroBlaze (embedded, NOMMU) arch.
Like some other nommu archs, we typically mount root on an MTD RAM
partition (either CRAMFS or ROMFS).
All of this is working fine on 2.6.19 plus SnapGear 2.6.19-uc0-bigpatch
NOMMU patchset.
However, since coming forward to 2.6.20 (plus equiv. SnapGear patchset)
mount_root is failing.
Problem solved. An error in the arch link script resulted in the
initcall_rootfs initcalls to not be invoked - thus the stub init_ramfs
wasn't mounted, and /dev didn't exist.
