driver provides support for the GPIO and
LEDs as implemented by the Xilinx Spartan FGPA integrated into the Soekris
net6501 programmed with the default bitstream found in the BIOS.
Two standard gpio(4)
provided, one for the 16 real pins which can be configured as either inputs or
outputs and another with 2 output-only pins that map to the error and ready
LEDs respectively. Both may be used with

If the Xilinx FPGA is programmed with a different bitstream, the driver will
likely not function.
