[POWERPC] Use embedded libfdt in the bootwrapper This incorporates libfdt (from the source embedded in an earlier commit) into the wrapper.a library used by the bootwrapper. This includes adding a libfdt_env.h file, which the libfdt sources need in order to integrate into the bootwrapper environment, and a libfdt-wrapper.c which provides glue to connect the bootwrapper's abstract device tree callbacks to the libfdt functions. In addition, this changes the various wrapper and platform files to use libfdt functions instead of the older flatdevtree.c library.

powerpc/boot/fdt: Add little-endian support to libfdt wrappers For epapr-style boot, we may be little-endian. This change implements the proper conversion for fdt*_to_cpu and cpu_to_fdt*. We also need the full cpu_to_* and *_to_cpu macros for this.

powerpc: Update in-kernel dtc and libfdt to version 1.2.0 Some time ago, a copies of the upstream dtc and libfdt sources were included in the kernel tree to avoid having these as external dependencies for building the kernel. Since then development on the upstream dtc and libfdt has continued. This updates the in-kernel versions to match the recently released upstream dtc version 1.2.0. This includes a number of bugfixes, many cleanups and a few new features. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
