Setup and use GPIOs on a Cubietruck

Cubietruck is also known as Cubieboard 3

Note: This file documents just what I did, first of all as a note for myself. So this is not primarily intended as a tutorial. Because it still might be helpfull, I uploaded it. The GPIO function is now confirmed to work, tested with my multimeter, but I am still waiting for my jumper cables to arrive, so I can use them securely.
