1 U-Boot for the Bachmann electronic GmbH OT1200 devices 2 3 There are two different versions of the base board, which differ 4 in the way ethernet is done. The variant detection is done during 5 runtime based on the address of the found phy. 6 7 - "mr" variant 8 FEC is connected directly to an ethernet switch (KSZ8895). The ethernet 9 port is always up and auto-negotiation is not possible. 10 11 - normal variant 12 FEC is connected to a normal phy and auto-negotiation is possible. 13 14 15 The variant name is part of the dtb file name loaded by u-boot. This 16 make is possible to boot the linux kernel and make use variant specific 17 devicetree (fixed-phy link). 18 19 In order to support different display resoltuions/sizes the OT1200 devices 20 are making use of EDID data stored in an i2c EEPROM. 21
