2024-12-02Enable legacy 8254 timer on ThinkPad T480Leah Rowe
I also enabled this on T480S, because otherwise SeaBIOS hung. Enabling it shouldn't cause any harm on the T480, though Mate did say that his machine seemed to work with my setup. However, I believe that was when I gave him the ones that lbmk built with the VGA ROM. Now it builds with libgfxinit, because Mate was able to fix libgfxinit on this machine.

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>

This uses the excellent deguard utility, written by the excellent Mate Kukri. A few bugs but it mostly works. Documentation to come shortly, in lbwww.git. Signed-off-by: Leah Rowe <leah@libreboot.org>
