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.

+![x230s_bc_removed](x230s_bc_removed.jpg)
+
+* Base cover
+
+Its [Hardware Maintenance Manual](https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/x230s_hmm_en_0c10860_01.pdf) could be used as a guidance of disassembly.
+
+The SPI flash chip (W25Q128.V in thr form of SOIC-8 for mine) is located at the circled place. Unlike [most Ivy Bridge ThinkPads](Ivy_Bridge_series.md), X230s has a single 16MiB SPI flash chip.
+
+The general [flashing tutorial](../../flash_tutorial/index.md) has more details.
