You might have noticed I applied parts of your patches, namely 1/4 and
the bulk of 3/4. A git rebase should make your patches a bit smaller and
should make you less dependent on future ppc changes.

Generally smaller patches are easier to review and will make merging
your series faster, so it would be nice if you could split this up a bit
more. This is especially important for the parts of the patches that
affect other users like mpc5200 aswell.

Sorry for not replying with a more detailed review, but your patch is
quite big and my spare time is rather small at the moment.

Thanks
 Sascha
