[PATCH 00/20] FDT clean-ups and libfdt support

From: Rob Herring <robh at 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. 

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.

A branch is available here[1]. Please test! I've compiled on arm,
arm64, mips, microblaze, and powerpc and booted on arm and arm64.
