2024-12-02	Add SPD support for onboard ThinkPad T480S RAM	Leah Rowe
	Patchset 20 from: https://review.coreboot.org/c/coreboot/+/83274/18..20 Updated to that. A bunch of changes I made locally have been copied here, thus removed from lbmk. The previous setup in lbmk was to have only the DIMM slot work, on the ThinkPad T480S, without setting up SPD for the onboard RAM> Mate Kukri reverse engineered the scheme by which the SPDs are chosen at boot, based on the wiring of the board. This should just about match the way Lenovo did it in their firmware. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-12-02	NEW MAINBOARD: ThinkPad T480S	Leah Rowe
	Added t480s delta to deguard, for MFS config. Updated coreboot/next to latest t480 patch set, which includes t480s. This porting was done by Mate Kukri. also includes experimental t480s support Also added a data.vbt file (not in the gerrit patch) for the T480s. I had to turn on 8254 legacy timer on t480s, otherwise SeaBIOS would hang. Same issue I saw on OptiPlex 3050 Micro. Minor issue: On S3 resume, nvme0n1 for example got renamed to nvme0n2. This caused a crash if running Linux from the nvme. I confirmed this via live USB distro. So this port will need some tweaking before it can be considered stable. Also uses libgfxinit, which Mate recently fixed. I'm going to enable libgfxinit on regular T480 next. Signed-off-by: Leah Rowe <leah@libreboot.org>
