mb/lenovo: add Lenovo ThinkPad X131e (Intel)
The Intel version of ThinkPad X131e can ship with Sandy Bridge or
Ivy Bridge processors. The mainboard uses 8MiB+4MiB flash chips, with
the 8MiB chip containing the IFD and ME, and the 4MiB chip containing
the BIOS. The flash chips can be accessed with an external programmer.
This port was primarily created using autoport, with some parts adapted
from lenovo/x230 and google/stout.
Tested and working:
- Machine type 3367AH5 / Intel Celeron 887 (Sandy Bridge)
- Boots Debian GNU/Linux 9.2 (Linux 4.9.51) via SeaBIOS
- Boot from internal SATA and USB
- Native RAM init
- Native VGA init
- libgfxinit
- VGA and HDMI display output
- Keyboard, trackpoint, touchpad
- Audio (speaker, headphones)
- Ethernet (Realtek)
- Display backlight
- USB 3.0 ports
- "Always on" USB port (EHCI debug)
- SD card reader
- Webcam
- Fan and temperature sensors
- ACPI S3 (Sleep)
- CMOS
- TPM
Not tested:
- WLAN/Bluetooth (Broadcom)
- WWAN/mSATA (no card)
- Other operating systems
Not working or not implemented:
- Fn keys
- ACPI S4 (Hibernation) "Image mismatch: memory size"
