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.
