NAME
soekrisgpio —
Soekris net6501 GPIO and
LEDs
SYNOPSIS
soekrisgpio0 at isa? port 0x680
gpio* at soekrisgpio?
DESCRIPTION
Thesoekrisgpio 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).

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