Coreboot v3 assumes a payload will not return. That means you can't rely
on any functions provided by coreboot. However, you could introduce
another stage (stage3) with access to the shared functions. Almost
everything with "struct device" lives in stage2 and is not shared, so
that might be a problem as well.

I'd suggest to post your current state (once the code has been released)
before you do any further work. Design decisions are easier once the
code is out there.

Carl-Daniel
