From: Rob Herring <robh@kernel.org>
This is a series of clean-ups of architecture FDT code and converts the
core FDT code over to using libfdt functions. This is in preparation
to add FDT based address translation parsing functions for early
console support. This series removes direct access to FDT data from all
arches except powerpc.
The current MIPS lantiq and xlp DT code is buggy as built-in DTBs need
to be copied out of init section. Patches 2 and 3 should be applied to
3.15.
Changes in v2 are relatively minor. There was a bug in the unflattening
code where walking up the tree was not being handled correctly (thanks
to Michal Simek). I re-worked things a bit to avoid globally adding
libfdt include paths.
A branch is available here[1], and I plan to put into linux-next in a few
days. Please test! I've compiled on arm, arm64, mips, microblaze, xtensa,
and powerpc and booted on arm and arm64.

The octeon FDT code can be simplified by using
unflatten_and_copy_device_tree function. This removes all accesses to
FDT header data by the arch code.

The existing code is buggy because built-in DTBs are in init memory.
It is also broken because the reserved bootmem was then freed after
unflattening, but the unflattened tree points to data in the flat tree.
Fix this by using the unflatten_and_copy_device_tree function.
This removes all accesses to FDT header data by the arch code.
