Good day Rudolf,
This page [1] tells that you have developed a open source firmware replacement of AMD IMC firmware and it is available under request. Please tell, did it made to a coreboot? If not, 1) why? (stability problems, or something else) 2) is the source code available somewhere publicly? I have Lenovo G505S coreboot-supported laptop with AMD Richland 15h CPU (A10-5750M) and it is probably using this IMC blob - thats why I am curious
