[PATCH] Add Flat OF tree support.

Hi all.

As you well know, as part of the ongoing cleanup of the linux trees
regarding PPC, it has been decreed that the preferred way to pass 
bootloader information shall be the flat OF tree.

The following patch (broken in two parts), implements just that.

Please be aware that in order to test it, you'll need a fairly recent
dtc tool, which is available by git at

  rsync://ozlabs.org/dtc/dtc.git

The xxd binary dumper is needed too which I got from

  ftp://ftp.uni-erlangen.de/pub/utilities/etc/xxd-1.10.tar.gz

Linux patches will follow...

Awaiting comments.
