|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.
