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.).
