Subject: [PATCH 1/2] drivers: of: implement overlay support Subject: [PATCH 2/2] drivers: of: implement overlay support
Origin by Jan Luebbe: Origin patches are from Jan Luebbe.
http://lists.infradead.org/pipermail/barebox/2015-March/022674.html
I rebase the patches and fix the resolve for __local_fixups__, they This is based on Pantelis Antoniou's overlay support for the kernel. It
was wrong copy/ported from linux kernel. 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.
