Hi Nick, I think all of these are actual system firmware, not linux-firmware, as far as I can tell from the upstream report from AMD. Can you please confirm? https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7009.html
Possible, but I'm not certain. Lets consult with Alex.

I think it is "linux-firmware" being loaded to the CPU during system boot.

Generally "platform initialization firmware" would be very early boot, AKA the UEFI system firmware, it also mentions access to the SPI flash, which is where the system firmware is stored, and that needs to be blocked long before the OS begins to boot else it could be compromised long before Linux loads the CPU microcode (and it's generally not something you'd patch in microcode) or someone could even block the microcode load. Can we get clarification from whoever supplied the AMD Doc.
Sure, I just reached out to AMD. Waiting to hear back.
Confirmed as UEFI.
This is a UEFI firmware update from the device vendor, not an update in linux-firmware.
