While there is the AMD openSIL project for open-source CPU silicon initialization for platforms moving forward with plans to ultimately replace AGESA and be more friendly toward the likes of Coreboot, for those on aging AMD Bulldozer and Piledriver era platforms there is some updated open-source firmware available thanks to an independent free software project.

For those that don’t remember or weren’t around back in the 2011 timeframe, back then AMD was initially promoting Coreboot and putting out open-source AGESA code for the processors/platforms of the time before running into their financial difficulties and abandoning those efforts. But with that open-source code still being available and prior a Coreboot port to the ASUS KGPE-D16 and other Opteron server motherboards of the time, 15h.org has been building off that to provide more robust open-source firmware support for these aging Bulldozer/Piledriver platforms.
