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
