The 'xtfpga' board is actually a set of FPGA evaluation boards that can be configured to run an Xtensa processor.
- Avnet Xilinx LX60
- Avnet Xilinx LX110
- Avnet Xilinx LX200
- Xilinx ML605
- Xilinx KC705
These boards share the same components (open-ethernet, ns16550 serial, lcd display, flash, etc.).

This should be in drivers/video and use driver model (UCLASS_VIDEO).
Ok, will move.

Shouldn't this go in the device tree? See show_board_info().
It can, but we don't have OF_CONTROL enabled in the default XTFPGA configuration. One reason is that otherwise it wouldn't fit into the LX60 board.

Ok.
