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.).
