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