I for now kept the old way for the GPIO. I did not add the new options. 
Some other things where more important for the business things. But if 
you start the ugpio I will upgrade from ugpio to stm32 and then we can 
go to trunk. For me we can go to trunk with the stm32 in a few days, 
with or without EMAC support. I can add this easily as we parted the 
archives really good.

Yes, that might be the best way, so I have no open branches enymore and, 
if I see that right, I do not have to modify things that break up the 
whole Nut/OS even for other architectures. (I will have a special view 
to I2C, cause there changed the basic structure)

Yes, right idea. Try it first on the branch, then upgrade all 
architectures and let Harald run his build-everything script.
If that works, merge back to trunk.

Hehe, that was the intention!
