mb/clevo/tgl-u: add new board L14xMU
Add new board Clevo L14xMU (TGL). GPIOs were configured based on schematics. Tested and working: - On-board RAM (M471A1G44AB0-CWE) - DIMM slot (tested Crucial CT16G4SFD8266.16FJ1 / MTA16ATF2G64HZ-2G6J1) - Graphics (GOP driver), including HDMI - Keyboard - I2C touchpad (including interrupt) - TPM (with interrupt on Windows, only polling on Linux [1]) - microSD Card reader - both NVME ports - Speakers - Microphone - Camera - WLAN/BT (CNVi) - All USB2/3 ports including Type-C - Thunderbolt detects my work laptop in TB Control Center (I couldn't test anything more due to security policy.) - TianoCore - internal flashing with flashrom on vendor firmware Note on TPM: The vendor sets Intel PTT to default-on in newer CSME images, which conflicts with the dTPM. Currently, there are two ways to make it work: 1) Boot vendor firmware once to let it disable PTT via CSME firmware feature override. 2) Use Intel Flash Image Tool (FIT) to set "initial power-up state" to disabled. Boots fine: - Debian testing, unstable (Linux 5.16.14, 5.17.0-rc6) - Windows 10 21H2 (Build 19044.1586) Untested: - Thunderbolt (see above) - Type-C DisplayPort - S-ATA Doesn't work: - TPM interrupt on Linux [1] - All EC related functions - EC driver is WIP - WLAN/BT (PCIe) - gets detected but can't be enabled - 3G/LTE (not powered without EC driver) - Fn-Keys - S0ix - UCSI - Fan control - Battery info [1] https://lkml.org/lkml/2021/5/1/103 Change-Id: I4c4bef3827da10241e9b01e12ecc4276e131a620 Signed-off-by: Michael Niewöhner <foss@mniewoehner.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/59548 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Arthur Heymans <arthur@aheymans.xyz>
