[coreboot] Configuration for Apollo Lake FSP (Github/MR5)

[Nico Huber]

Hi,

has anyone made good or bad experience with the Apollo Lake FSP
currently on Github (it's the MR5, afaict)? FSP-M never returns
for me and I have no post-code display :-/

I tried both XIP and loading into CAR, same result. Maybe it's
still something wrong with my configuration. If anybody had suc-
cess with this binary, please share your `.config`.

My FSP-M UPDs could be wrong as well. But can that result in a
hanging FSP? Do we have to expect undefined behaviour because
of bad memory parameters?
