Open Firmware Flat Tree and usage.
----------------------------------

As part of the ongoing cleanup of the Linux PPC trees, the preferred
way to pass bootloader and board setup information is the open
firmware flat tree.

Please take a look at the following email discussion for some
background.

The generated tree is part static and part dynamic.

There is a static part which is compiled in with DTC and a dynamic
part which is programmatically appended.

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
