[PATCH v2 00/21] FDT clean-ups and libfdt support

[Rob Herring]

From: Rob Herring <robh@xxxxxxxxxx>

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.
