If this is verified to actually be doing what it says I'll be intentionally jumping the gun on updating my haswell system and moving to AMD.
It's not. In one motherboard's BIOS/UEFI interface the option is phrased as "BIOS PSP Support" and on ASRock AB350 Gaming-ITX/ac description for this flag is Enable Disable BIOS PSP driver execution (including all C2P/P2C mailbox. Secure S3. fTPM Support)
I'm not at all familiar with any of those terms (C2P/P2C mailbox. Secure S3. fTPM Support)
What exactly do those things do?
Heck, if amd released raven ridge with this option my next laptop might actually be a A model thinkpad.
I honestly can't remember the last time I considered buying an AMD based laptop... Exciting times we live in haha
Better headline: "Rumors on Reddit lead tech journalist to assume that AMD has done something right"
