Btw, I like the way we do pin mux in U-Boot at the moment (*). Or 
better: I can't imagine a way how to do it even better without 
introducing other disadvantages. But I will enjoy to have a look to 
your changes ;) Maybe you can give us already an idea of how you like 
to change it?

(*) What I like:

Having everything in one file for each board. With this, you can get a 
complete overview of board's pin mux with looking only in one file. 
And you can see immediately for each pin what is configured and how.

Best regards

Dirk
