I think it would be awesome to have this via device tree as well as that
would be another step closer to allowing one u-boot binary for a group
of boards. However, that's clearly much more work. So for the short term
(and ideally the coming release)  i'd quite prefer this minimal change
to go in to unbreak bootz  and PXE on these boards.
