21f3fe2f7a [POWERPC] bootwrapper: Add get_path()
This will be used by the PlanetCore firmware support to construct
a linux,stdout-path from the serial node that it finds.

4674f2f339 [POWERPC] bootwrapper: flatdevtree fixes
1. ft_create_node was returning the internal pointer rather than a phandle.
2. ft_find_device_rel was treating a "top" phandle of NULL as an error,
rather than as the root of the tree.  The old, absolute ft_find_device
is removed, and the relative version is renamed to ft_find_device().

a9ec7669fc [POWERPC] bootwrapper: Make ft_get_parent() return a phandle, and NULL if already top-level.
Most of ft_get_parent() is factored out into __ft_get_parent(), which
deals only in internal node pointers.  The ft_get_parent() wrapper
handles phandle conversion in both directions (previously,
ft_get_parent() did not convert its return value).

It also now returns NULL as the parent of the toplevel node, rather than
just returning the toplevel node again (which made it rather useless in
loops).

6fb4efc68f [POWERPC] Add flatdevtree source
Add the latest version of the flatdevtree code and corresponding glue.

A phandle table now tracks values returned by ft_find_device().
The value returned by ft_find_device() is a phandle which is really
an index into the phandle table.  The phandle table contains the address
of the corresponding node.  When the flat dt is edited/moved, the node
pointers in the phandle table are updated accordingly so no phandles kept
by the caller become stale.

b2c5f61920 [POWERPC] Start arch/powerpc/boot code reorganization
This abstracts the operations used in the bootwrapper, and defines
the operations needed for the bootwrapper to run on an OF platform.

The operations have been divided up into platform ops (platform_ops),
firmware ops (fw_ops), device tree ops (dt_ops), and console ops
(console_ops).

The proper operations will be hooked up at runtime to provide the
functionality that you need.
