Hm, do you think it's absolutely necessary to make everybody work with
board-generic? It will require a lot of additional bindings to get rid
of all machine-specific code. I've just thought that on PowerPC we don't
have such strict rules: if some boards are really similar they share
common machine file but if we need something specific for the new board
we can create it's own machine file.

That turned to be not such a big problem. Device is not present so we
have tons of error messages but somehow it works.

The bigger problem is that we have different regulator chip attached.
How am I supposed to register supplies/consumers data with it? Does
anybody working on DT bindings for the regulator framework?
