imx6: add Bachmann OT1200 board
This patch adds support for the OT1200 series of devices. Following components are used in u-boot: + ethernet + i2c + emmc + gpio For more details see README. Changes v1 > v2 - make use of enable_cspi_clock(..) - fix usage of OUTPUT_40OHM define - added README Changes v2 > v3 - improve spelling in README - added own copy of mx6q_4x_mt41j128.cfg Signed-off-by: Christian Gmeiner <christian.gmeiner@gmail.com>

+U-Boot for the Bachmann electronic GmbH OT1200 devices
+
+There are two different versions of the base board, which differ
+in the way ethernet is done. The variant detection is done during
+runtime based on the address of the found phy.
+
+- "mr" variant
+FEC is connected directly to an ethernet switch (KSZ8895). The ethernet
+port is always up and auto-negotiation is not possible.
+
+- normal variant
+FEC is connected to a normal phy and auto-negotiation is possible.
+
+
+The variant name is part of the dtb file name loaded by u-boot. This
+make is possible to boot the linux kernel and make use variant specific
+devicetree (fixed-phy link).
+
+In order to support different display resoltuions/sizes the OT1200 devices
+are making use of EDID data stored in an i2c EEPROM.
