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.)

I fried my mainboard because I tried to orient my chip by lining a blue dot on
the corner of my chip with a dot depicted on the chip datasheet. They
apparently have nothing to do with each other, and this is normal. Add
warning about this to the docs to hopefully spare others from a similar fate.

Initially, I wanted to move only the Kconfig DISPLAY_MTRRS into the
"Debug" menu. It turned out, though, that the code looks rather generic.
No need to hide it in soc/intel/.
To not bloat src/Kconfig up any further, start a new `Kconfig.debug`
hierarchy just for debug options.
If somebody wants to review the code if it's 100% generic, we could
even get rid of HAVE_DISPLAY_MTRRS.
