This isn't what GKI mandates. GKI requires that the SoC code is compiled
as modules, not that it is dissociated from its platform (which would
be completely pointless).

I don't deal with defconfig at all. That's a patch for the arm-soc 
people.

You might as well turn both drivers into modules. Saravana was working
on a set of patches to ease this transition.

Thanks,
