Add support for the iMX6 based conga-QMX6 family of Qseven modules.

This patch is based on Linux 3.0.35 from Congatec's kernel git reporitory

There has been a similar patch set from Lahoudere Fabien <fabien.lahoudere@openwide.fr>
last year adding a patch to the freescale kernel repository, but it seems more logical
to me to start from the manufacturer's repo (which might not have been availeable at
that time).

+This is the minimal buildroot support for the Congatec QMX6 Qseven CoM
+
+conga-QMX6 is based on the freescale iMX6 SoC. For more information please
+have a look at http://www.congatec.com/products/qseven/conga-qmx6.html
+
+The configuration is based on the currently latest kernel release from
+Congatec's git repository which is based on 3.0.35. The bootloader u-boot
+is preconfigured on the CPU module and does not need to be replaced.
+
+To build the default configuration you only have to:
+
+	make qmx6_defconfig && make
+
+You will need a microSD card of sufficient size and the first or only
+partition configured as Linux type.
+
+To transfer the system to the card you have zwo options:
+
+1.	$ sudo dd if=output/images/rootfs.ext2 of=/dev/sdX1
+
+2. 	only once: sudo mkfs.ext3 /dev/sdX1
+	$ sudo mount /dev/sdX1 /mnt
+	$ sudo tar xf output/images/rootfs.tar -C 
+	$ sudo umount /mnt
+
+Connect a terminal program to the rs232 connector marked "CONSOLE",
+insert the microSD card into the socket on the CPU module and power
+the board to watch the system boot.
+
+Booting from the SD card slot on the base board is currently not
+supported.
