Hmm... I have to look at the others. Probably a good idea.

OK, thanks, will check that out!

Most importantly I juts saw a remaining "//" comment - oops!

But how more readable should I do that? The pin is assigned to the gpio
system (which is IMHO a good idea) and those line should make it high
impedance. This has nothing much to do with kirkwood I think.

Well - sure, could take that too, OK.

Oh really? Which more exactly? I miss to see the difference with other
boards in the mach-kirkwood/ subdir.

Thanks for the hints!
