Soekris net6501 GPIO and LEDs
skgpio0 at isa? port 0x680
gpio* at skgpio?
skgpio 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) interfaces
are 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.
