configs/solidrun_clearfog_gt_8k: new defconfig

Add support for the SolidRun Armada 8040 based Clearfog GT-8K. This
board has the same processor as the Macchiatobin, so we can reuse the
Macchiatobin U-Boot and image definitions.

The kernel fragment enables drivers that are necessary to make
networking ports work (SFP, Ethernet port, and Ethernet switch).

+Intro
+=====
+
+The default configuration described below will allow you to start
+experimenting with the buildroot environment for the SolidRun Clearfog GT-8K
+based on the Marvell Armada 8040 SoC.
+
+This default configuration will bring up the board and allow shell command
+line access through the serial console.
+
+How to build
+============
+
+  $ make solidrun_clearfog_gt_8k_defconfig
+  $ make
+
+How to write the SD card
+========================
+
+Once the build process is finished you will have an image file named
+"sdcard.img" in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync
+
+How to boot the board
+=====================
+
+The Clearfog GT-8K can be setup to load the bootloader from different sources
+including eMMC, SPI flash, and SD-card.
+
+To select boot from SD-card the DIP switches in SW6 (at the bottom of the
+board) should be configured as follows:
+
+  SW6: 11010
+
+Insert the micro SDcard in the Cleargfog GT-8K and power it up.
+
+Serial console
+==============
+
+The serial console is accessible at the J27 pins header (TTL UART) with the
+following pinout (pin #1 is marked with triangle on the PCB):
+
+  pin #1: Ground
+  pin #2: Armada 8040 Rx
+  pin #3: Armada 8040 Tx
+
+Enable the switch (yellow) Ethernet ports
+=========================================
+
+To enable the Clearfog GT-8K internal switch port make sure to load the
+'mv88e6xxx' kernel module, and up the switch up-link port (eth2 by default):
+
+  modprobe mv88e6xxx
+  ifconfig eth2 up
+
+Then you can configure each switch port separately. These port are named
+'lan1' to 'lan4' by default. 'lan1' is closest to the USB port, while 'lan4'
+is closest to the blue Ethernet port.
