Hi Florian,

I don't have access to my IGEP board so I can test it right now but the patch
looks good to me.

In fact I wanted to use MTDPART_SIZ_FULL when added the NAND nodes since not all
IGEP boards have 512MB flash but I didn't know that a value of 0 meant that.

So thanks a lot for doing this!
