From d87277abbf70b7f29034a503689de47aba7e3052 Mon Sep 17 00:00:00 2001 From: Bill XIE Date: Fri, 8 May 2020 16:40:48 +0800 Subject: mainboard/lenovo/x230: Add ThinkPad x230s as a variant The code is based on autoport and that for X230. Major differences are: - Only one DDR3 slot - HM77 PCH - M.2 socket instead of mini PCIe - No docking - No TPM Tested: - CPU i5-3337U - 8GiB SO-DIMM - Camera - PCIe 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 PCIe - USB3 ports - libgfxinit-based graphics init - NVRAM options for North and South bridges - Sound - ThinkPad EC - S3 - Linux 4.9 within Debian GNU/Linux stable, loaded from SeaBIOS. Untested: - Touch screen, which is said to work under ubuntu but not debian.
