I'm actually fine with an approach like we are taking here. Come up
with something that works purely with linux-yocto, and then we can
start factoring and grouping the fragments with the help of people
closer to the h/w.

In particular as more Xilinx proprietary parts are open sourced, we'll
have the opportunity to tweak the configuration fragments to support
them properly/fully.

We do want the fragments in the centralized kernel-cache, just as long
as they are appropriated factored/grouped under a xilinx/ subdir where
it makes sense, and have more generic feature groupings available to
be shared in the more common directories.

What we have is a good start to that goal, so I'll get it merged and
we can start iterating on it in tree.
