- 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.
