The code is based on autoport and that for T430s
Tested:
- CPU i5-3337U
- Slotted DIMM 2GiB
- Soldered RAM 4GiB from samsung (There may be more models here)
- 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
- TPM1 on LPC
- EHCI debug on SSP2 (USB3 port on the left)
- Linux 4.9.110-3 within Debian GNU/Linux stable, loaded from
Linux payload (Heads), Seabios may also work.
Not tested:
- Fingerprint reader on USB2 (not present on mine)
- Keyboard backlight (not present on mine)
- "sticky_fn" flag in nvram
Not implemented yet:
- Fn locking in nvram (may not be identical to "sticky_fn")
- C-based native graphic init (since T431s has eDP instead of LVDS)
- Detecting the model of Soldered RAM at runtime, and loading the
corresponding SPD datum (3 observed) from CBFS (the mechanism may be
similar to that on x1_carbon_gen1 and s230u, but I do not know how
to find gpio ports for that, and SPD data stored in vendor firmware.)

This heading should not be a top-level heading, because it's not at the
top of the file.
Also remove the trailing colon, because it's unnecessary in a heading.
