Erm, not very complete actually. Enable DEBUG_LL to see
more early messages ... like the ones starting right
after the kernel decompression messages.

Also, re those udev-induced messages:

Remounting root file system...

You shouldn't need mtdblock unless you run JFSS2, so that's
the quick way to get rid of them: take that out of your
kernel configuration. Else, add "mtdblock*" to
the "KERNEL==... ; goto persistent_storage_end" check in

/etc/udev/rules.d/60-persistent-storage.rules

I understand the next version of udev will fix that.
