<p class="Pp">The <code class="Nm">soekrisgpio</code> 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.</p>
<p class="Pp">Two standard <a class="Xr">gpio(4)</a> 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 <a class="Xr">gpioctl(8)</a>.</p>
