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 pci-e
- no docking
- no tpm
Tested:
- CPU i5-3337U
- Slotted DIMM 8GiB
- Camera
- pci-e 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 pci-e
- USB3 ports
- libgfxinit-based graphic 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.
