A clarification. From the StoneyPI_1_3_0_A.ZIP file I've got under NDA is it possible to compile it and get the AGESA.bin file? For instance, for the fam15tn family the coreboot build process generates a libagesa.fam15tn.a file which is integrated in the final coreboot.rom file. Could it be possible to do the same from a PI family? The build process in coreboot is only prepared to use a wrapper and the AGESA.bin file, but maybe is it possible to generate the AGESA.bin from the zip file...

Hi Kyösti! Thanks for the info!
AMD contracted SilverBack for the tasks on StoneyRidge (and MerlinFalcon apparently). The source is a heavily modified StoneyPI package. You may get the unmodified one from AMD reps under NDA. Or pay SilverBack for the development you would be more capable of doing yourself, and you still might not get a license that allows distributing the work. There was a promise of scrubbing and relicensing StoneyPI source but... Let's just say legalities messed it up, I don't have the details.
Yes, the AMD reps we're in touch answer me to get in touch with SilverBack to get support :( We've been able to get a more recent StoneyPI_1_3_0_A.ZIP under NDA because I've seen this version fixed the issue:
EMBSWDEV-4487: System is not booting when memory is connected only to DIMM 1 slot
maybe related with our problem, but I don't know how to integrate this code into coreboot... And if you say that the current work in coreboot is from a heavily modified base from SilverBack I don't have any chance to make it work...
As for the the other blobs (MullinsPI, CarrizoPI, KaveriPI), those were either built at SAGE (R.I.P.) or AMD AES (R.I.P.) and I have been told the repositories and toolchains were never officially transferred to SilverBack's possession. In other words, even if you paid, SilverBack is not likely to work on those.
Then, no more options to get a working BIOS than SilverBack?
I believe we have talked before. Maybe it was about CarrizoPI? I was asking for commercial adopters around coreboot and binaryPI, in attempts to get to the same negotiation table with AMD management. Did You or Your manager ever respond?
Yes. I began asking in the coreboot mailing list about the Bettong mainboard. I added TPM support and tianocore to that demoboard. I remember the email and I answered it giving my support because we thought coreboot is the way to go to support our custom board.
