New AMD Processors Supported By Coreboot

While Coreboot support for systems with newer Intel CPUs is tough, Coreboot gained yesterday support for some new AMD CPUs.

AMD Family 15h Model 30 processors are now handled by Coreboot with the latest Git as of yesterday. The new AMD CPU code for Coreboot adds the basic support for Family 15h Model 30 CPUs but at least one initial limitation of this work is that S3 suspend/resume is not supported with this Coreboot code. It seems the Family 15h Model 30 includes AMD R-Series APUs as well as some A-Series APUs and the Opteron X series.

With this new CPU enablement in Coreboot, the open-source BIOS/UEFI replacement was tested on an AMD "Lamar" consumer reference board. The Lamar CRB is an older board and in researching it have found traces on OpenBenchmarking.org of Lamar CRB benchmarks going back about a year.
