[PATCH 0/3] commands: of_diff: support applying fixups on arbitrary device trees

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

of_diff - + is quite useful to find what fixups barebox would apply to
its own device tree. But for some cases, like barebox-state or OP-TEE
reservations, the nodes that would be fixed up into the kernel device
tree already exist within the barebox device tree and wouldn't be shown
by of_diff - +. To make them visible, let's redefine +:

  - Previously, it always meant the fixed up barebox DT
  - Now, it means the other DT with fixups applied

That way, of_diff - + continues to work, but kernel DTs can now be
diffed against their fixed up version by doing:

   of_diff /mnt/tftp/afa-oftree-myboard +
