To my knowledge we don't have any platforms with those CPUs so I
wouldn't have the ability to test it. I also don't think I'd be a good
candidate for that kind of exercise (both in terms of experience and time).
For Lenovo platforms I'd be looking at Whiskeylake, Cometlake and
Tigerlake based (using SOF), and my understanding was the signed
firmware is required. At least when I've tried unsigned previously the
firmware does not load.
If somebody more knowledgeable can correct me (with details) that would
be great.
Mark
