Patches from AMD began back in February and they have blogged about the work here and here.
Marc Jones, a Coreboot developer at Sage Electronic Engineering, was involved with this latest AMD code release and he writes to Phoronix: "The release includes support for the Embedded G-Series Fusion processor (fam14 and sb800). It also included Fam10 code, which coreboot already had some support for. AMD has really stepped it up this time. The code is the same code that BIOS vendors get, and not a port or limited support that coreboot has received from AMD in the past."
