Subject: mb/clevo/tgl-u: add new board L14xMU
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

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
