From 012ef7735d6878ef63aa0315863636bfb88e6c1f Mon Sep 17 00:00:00 2001 From: Bill XIE Date: Thu, 29 Nov 2018 20:37:35 +0800 Subject: mainboard/lenovo/t430s: Add ThinkPad T431s as a variant The code is based on autoport and that for T430s Tested: - CPU i5-3337U - Slotted DIMM 2GiB - Soldered RAM 4GiB from samsung (There may be more models here) - Camera - pci-e and usb2 on M.2 slot with A key for wlan - sata and usb2 (no superspeed components) on M.2 slot with B key for wwan - On board SDHCI connected to pci-e - USB3 ports - libgfxinit-based graphic init - NVRAM options for North and South bridges - Sound - Thinkpad EC - S3 - TPM1 on LPC - EHCI debug on SSP2 (USB3 port on the left) - Linux 4.9.110-3 within Debian GNU/Linux stable, loaded from Linux payload (Heads), Seabios may also work. Not tested: - Fingerprint reader on USB2 (not present on mine) - Keyboard backlight (not present on mine) - "sticky_fn" flag in nvram Not implemented yet: - Fn locking in nvram (may not be identical to "sticky_fn") - C-based native graphic init (since T431s has eDP instead of LVDS) - Detecting the model of Soldered RAM at runtime, and loading the corresponding SPD datum (3 observed) from CBFS (the mechanism may be similar to that on x1_carbon_gen1 and s230u, but I do not know how to find gpio ports for that, and SPD data stored in vendor firmware.)
