I think we can make it clear to AMD that we are grateful for AGESA and their support, and the way they have helped us to get to a good place in terms of code; and, further, we can now offer a better option, with code that really fits well into coreboot.
I don't see demoting AGESA as a bad thing; it's a good thing. AGESA got us to where we are, and now we take the next step: code that is well integrated. In fact I think we're all giving AMD a huge vote of confidence by making the effort to make their chips fit really well into coreboot, instead of being half-in/half-out. This is going to be a big improvement.
We're not tossing AMD out; we're inviting them into the living room, with a warm fire and a nice place to sit down and relax :-)
