From: "Borislav Petkov (AMD)" <bp@xxxxxxxxx> Hi all, these are Rik's patches from here: https://lore.kernel.org/r/20250226030129.530345-1-riel@xxxxxxxxxxx with a bunch of dhansen's and mine edits ontop. Some stuff is still in-flight but I'm sending the current state because a bunch of things have changed and we'll need a good base to discuss the remaining changes pending. Preliminary build and boot tests look good but that doesn't say a whole lot. Thx.
