[coreboot] AGESA PI for Olivehill+

[Wim Vervoorn]

Hello Kyosti,

I do agree with you that it is much easier and straight forward to change memory parameters when you are using the source agesa but it is definitely possible to do this for the binary agesa as well. You can provide the binary AGESA with external tables during run-time.

I do agree with your other points though. 


Best Regards,

Wolfgang,

with the PI source you are in a better position to develop than any of us in the community contributors. I hope you would push your AMD FAEs to get the API fixed, if you indeed are currently unable to make FT3b work with on-board memory, with the pre-built binaryPI files AMD AES pushes to coreboot 3rdparty / blobs. If you do not do that, You will need to rebase your local changes and rebuild PI part of your firmware image part every time AMD updates their MullinsPI package. 

I am complaining about the current state of things here as well:

  http://review.coreboot.org/#/c/9386/


Just beware that what I consider as the official documentation, taken from AMD AES website about PI and coreboot, still states the following in FAQ.462:


"Note that the customer MAY NOT ship product with the nonscrubbed PI, as no such rights are provided in the NDA or otherwise. The customer must convert to the IP-scrubbed PI for production."


I have tried to have AMD AES to fix/revisit/confirm this statement for 6 months now, since it has not been updated after all the binaryPI invention our partners in crime came up with. I have contacted AMD AES both directly and via their EMEA FAE, but they have pretty much zero response rate nowadays towards coreboot community.


Kind Regards,
Kyösti Mälkki
