We have yet to see this board function in all it's prime with the current AGESA, now with this (code revamp) thrown into the mix....... I wonder.
This, assuming Threadripper will also get the same "love", 1.0.0.6+/7 is Ryzen 3/5/7 codebase. TR is on version 1.0.0.3, I'm sure the code shares lots of things, but it is different and does not have nor will it have any APU code in it for obvious reasons.
Folks keep comparing Ryzen AGESA with TR on a version basis but this is not the case. 1.0.0.3 would probably be equivalent to 1.0.0.6+ on Ryzen as far as memory tweaks and fixes goes.
In some ways TR AGESA is probably simpler than AM4 stuff. The current code for Ryzen already has to support more than one type of CPU/APU with more on the way soon(Ryzen based Apu). TR4 does not.
