can you please elaborate which binary caused this issue and why you sus-
pect that it's related to -U SKUs. There are two versions on github by
now. One is tagged KabylakeFsp0001, the other (current HEAD) is called
"Gold release" with no tag at all (8267cde097).

We use KabylakeFsp0001 here with Skylake-H and, IIRC, Purism uses it
with Skylake-U.

In my experience, we'll never figure that out. Even when they release
a new version on github, you can never tell to which version of the
(original?) FSP it corresponds (unless you find the exact same binary,
of course).
