I have not enabled livetree for any of the boards I have. So I just
modeled this using the existing ./common/fdt_support.c!

I do agree we should start using livetree in fdt helpers, if I
understood it correctly, it should work for both flattree and
livetree. Perhaps we could have another patch series after this? I am
preparing another Kirkwood board support patch that I could hold off
submitting and enable livetree to use that as a vehicle for testing.

Thanks,
Tony
