Sorry for jumping in to the middle of the discussion, but why does a *new*
framework even bother defining an interface for board files?

Can't we just drop any interfaces for platform data passing in the phy
framework and put the burden of adding those to anyone who actually needs
them? All the platforms we are concerned with here (exynos and omap,
plus new platforms) can be booted using DT anyway.
