Maybe update the description to say "This fixes a regression with
device tree based booting compared to legacy booting for n900 to
make the n900 legacy user space to also work with device tree based
booting".

It would be nice to get these two in as fixes after -rc1 assuming
people have no objections to it. So please upload this one also
into Russell's patch system after no more comments:
