I have used the LPC for an interface which I built (I have previously
promised to put the details onto the Voyage Wiki, and will eventually do
that).  Attached is the program which I use to "enable" the LPC for
simple I/O on the 6 available bits.  There are lots of comments to show
what (I think) I am doing.  Once the port is "enabled", you can access it
with straight C port-IO (e.g. 'inl' and 'outl' to the GPIO reg port at
0xf410).

Hope it might help.

Regards,
Bill
