Oh well.

I'm not sure I agree about feasible. I agree it's not worthwhile
though. You know your customers best, but from my experience with
embedded customers, more configurability is better. :)

Yes of course.

I guess you already know that PCI interrupts are locked to whatever
the VSA blob configures for the virtualized devices. I do agree about
disabling and I/O and interrupts as far as possible..

This is a good point. It could make sense to have hooks already in
the bootblock.

I know. This is one part of coreboot "infrastructure" that I think
needs some improvement. A first step would be interrupt routing.

It might also be nice to make it a little easier to use devicetree.cb
from the coreboot code.

That makes sense. Thanks for clarifying.
