It's somewhat unclear form the slides, but it looks like these target the 17h (ryzen) psp. Do the same exploits also affect earlier versions?
I think these attacks are possible because of the general flaws at PSP architecture, so yes they should also affect e.g. the late 16h systems (Puma). Early 16h systems (Jaguar) are safe because they don't have a PSP, so my ASUS AM1I-A with Athlon 5370 is safe - although maybe not yet, because I'm too busy with G505S and still haven't flashed a coreboot there! Just collecting the dust at the moment... :P

As for the patching, afaik AMD has released patches for all of these, but I haven't seen any patches for my 16h systems.
Almost all the coreboot-supported AMD 16h boards are AMD _early_ 16h (so no PSP). Please tell what 16h systems do you have, maybe they don't have a PSP at all?
