mb/foxconn/d41s: Add mainboard

This supports the Foxconn d41s, d42s, d51s, d52s.

The following is tested (SeaBIOS 1.12 + Linux 4.9) and works:
- COM1
- S3 resume (with SeaBIOS needs sercon disabled)
- Native graphic init on VGA output
- SATA
- USB
- Ethernet
- PS2 keyboard

The base for this mainboard port was the Intel D510MO port.

+# Foxconn D41S
+
+This page describes how to run coreboot on the [FOXCONN D41S] desktop from [FOXCONN].
+The D42S, D51S, D52S are compatible boards with the difference being the CPU.
+
+## Building coreboot
+
+The default options for this board should result in a fully working image:
+
+	# echo "CONFIG_VENDOR_FOXCONN=y" > .config
+	# echo "CONFIG_BOARD_FOXCONN_D41S=y" >> .config
+	# make olddefconfig && make
+
+
+## Flashing coreboot

+### Internal programming
+
+The SPI flash can be accessed using [flashrom].
+
+### External programming
+
+The easiest to flash externally is to simply extract the SPI flash from its socket.
+To do this gently take the SPI flash out of its socket and flash with your programmer.
+
+**NOTE: Don't forget to set the WP# AND HOLD# to 3V.**
+
+**NOTE2: Make sure to reinsert it in the right direction afterward**
+
+**Location and orientation of the SPI flash socket**
