Foxbone_syscall is the software interface of vhdl
http://www.acmesystems.it/?id=124

The gpio_syscall are a direct way to read/write gpio bits but the same
function (an official supported inside kernel)  can be obtain with
ioctrl on /dev/gpio*  http://www.acmesystems.it/?id=22

Both the foxbone_syscall and gpio_syscall are not necessary if you
only want to use gpio.
The foxboard-utils readbit, setbit and i2ccmd
(http://crisos.tuxfamily.org/dokuwiki/doku.php?id=documentation:other:i2ccmd)
are using the normal gpio interface.
