In response to new device tree code in the kernel, OLPC will start
using it for probing of certain devices. However, some firmware fixes
are needed to put the devicetree into a usable state.
Retain compatibility with old firmware by fixing up the device tree
at boot-time if it does not contain
Make OLPC fully depend on device tree, and use it to identify the OLPC
platform details. Some nodes are exposed as platform devices where we
plan to use device tree for device probing.

The x86 folks should probably be cc'd as well..
Overall, this looks good, just a few minor issues below.

New in v2:
Changed many device tree bindings. They should be closer to the
standard naming scheme now.
Editing of the template device tree is done in the flattened form
using libfdt.
Standard platform driver functions used in preference to the
of_platform variety.
v1:
Background: The Octeon
Currently all paths passed to of_find_node_by_path() must begin with a
'/', indicating a full path to the desired node.
Augment the look-up code so that if a path does *not* begin with '/',
the path is used as the name of an /aliases property. The value of
this alias is then used as the full
