Well, we still consider FSP support experimental. As you might have
imagined, the concept is new to us, we're still trying to wrap our heads
around it. We're not even sure if we'll keep FSP in the long run,
considering we have more native support for the FSP parts.

As far as the configuration goes, if you start with a blank .config, and
select the board you want, the defaults should be able to produce a
working image.

How did you think of unifying CC2 and EL2? One uses the FSP path, while
the other one does not. We still keep the FSP vs non-FSP paths separate,
although I think converting a board from one path to the other should be
relatively simple. I would start by editing the configuration in
src/mainboard/intel/<boardname>/ (Kconfig and devicetree.cb), and go
from there.
