Several people found this code (including me). But I don't think it's a good idea right now to merge because it is better to leave these things to the BIOS. It's unlikely that AMD will regularly release "open" microcode updates anyways, and moving them between BIOSes seems a bit dangerous to me (often you likely need to change some magic MSRs too or you could have some side effects). Overall it seems to be too dangerous to do in a standard kernel.
Also I suspect the driver won't work very well on SMP.
