Soekris net6501 GPIO and LEDs

gpio* at soekrisgpio?
The soekrisgpio
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 gpioctl(8).
The soekrisgpio
driver first appeared in
NetBSD 7.0.
The soekrisgpio
driver was written by
Matt Dainty
<matt@...> and imported from
a patch for OpenBSD to
NetBSD by
Frank Kardel
<kardel@NetBSD.org>.
If the Xilinx FPGA is programmed with a different bitstream, the driver will likely not function.
