It is similar to X200s, with U-series CPU, slightly different gpio
setup, no docking support, and no superio chip.
Tested:
- CPU Core 2 Duo U9400
- Slotted DIMM 4GiB*2 from samsung
- Camera
- pci-e slots
- sata and usb2
- libgfxinit-based graphic init
- NVRAM options for North and South bridges
- Sound
- Thinkpad EC
- S3
- Linux 4.19.67-2 within Debian GNU/Linux stable, loaded from
Linux payload (Heads) and Seabios.

The port is based on the x201 / t410s.
2537-vg5 / i5, no discrete gpu
Tested and working:
* Native raminit
* Native gfxinit
* Booting Seabios 1.12.1
* Booting from EHCI
* Running GNU/Linux 5.0.0
* No errors in dmesg
* EHCI debug on the devices left side, bottom-right
* Keyboard
* Fn keys (Mute, Volume, Mic)
* Touchpad
* TPM
* Wifi
* Sound
* USB
* Ethernet
* S3 resume
* VBOOT
Testing in progress.
Untested:
* VGA
* Displayport
* Docking station
Bugs:
* AC adapter can't be read from ACPI
* TPM not working with VBOOT and C_ENV BB
Details for flashing externally:
1. Disconnect all power
2. Connect the external flasher
3. Connect the power cord (This fixes internal power control)
4. Remove the power cord

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

Also remove the trailing colon, because it's unnecessary in a heading.
