My understanding is that "zynqmpimage" only works if you have one
"partition", so if you're passing the ATF or other partition data I
think that you have to use "zynqmpbif".

How's this sound?:
===
The ZynqMP Boot Image Format allows specifying the register
initialization file with the "[init]" attribute.  Since this
feature is already supported by the "zynqmpimage" backend, this
commit implements a binding to that existing support.

Please accept my apologies again for messing that up the first time around.
