Looks pretty good.  Just a couple of questions.

Filled in by U-Boot itself?  Or by a cuboot wrapper? (which I can't find
in the patches.)

This interrupt is really rising edge?  Just double checking.

You have no ranges property for the ebc parent node.  Is if filled in by
U-Boot?  If so, please add a comment because otherwise I don't see how
this mapping will work.

Does U-Boot (or the wrapper) poke these values as well?
