Mike Banon:
If you know, please tell the AGESA versions of fam15h/fam16h AMD vendorcode. For fam14h it is v1.103 - so no questions - but for fam15h and fam16h it says v0.001: #define AGESA_VERSION_STRING {'V', '0', '.', '0', '.', '0', '.', '1', ' ', ' ', ' ', ' '}
From hacking on the code itself, it seems f16kb is a newer fork of AGESA than f15tn, which is newer than f14. For example, a couple failures to initialize a variable in f14 were already addressed in f15 and f16, and the MMIO allocation seems a bit more fleshed out in f16 than f15.
Also, I wonder if there's an AGESA changelog somewhere, to learn if any security vulnerabilities or bugs have been fixed since AMD has shared some AGESA revision with coreboot. If these problems are serious enough, I could try to ask AMD to share the latest AGESA code available for these platforms.
There are AGESA release notes for the PI blobs, such as 3rdparty/blobs/pi/amd/00730F01/FT3b/AGESA_Release_Notes.txt. Not finding an equivalent under vendorcode (or generic internet searches)...
