Subject: [PATCH 2/2] drivers: of: implement overlay support
Origin by Jan Luebbe:
http://lists.infradead.org/pipermail/barebox/2015-March/022674.html
Origin patches are from Jan Luebbe.
I rebase the patches and fix the resolve for __local_fixups__, they
was wrong copy/ported from linux kernel.
This is based on Pantelis Antoniou's overlay support for the kernel. It
has been simplified by leaving out transaction support, locking and
other details required by the Linux DT support.
I merge the overlay code from oftree into own command: of_overlay
Pascal Vizeli fix some parts of resolver they was wrong ported from
linux source.
