Personally I believe that every software task should setup as much as possible from what it knows to be needed for its own work. For a serial program this includes setting the baud rate and the communications parameter like 8/n/1. >>> For each of the three uarts, the device tree has the following line: >>> >>> current-speed = <0>; /* Filled in by U-Boot */ >> >> Checking current U-Boot code, I believe this comment is simply >> wrong.

This may very well be the case. An answer can probably be found on the linux ppc mailing list[1] ;) >>> Sorry for the silly question! >> >> I don;t think its a silly question, but I also think that you do not >> need the configuration ;) >> >> Cheers >> Detlev > > Thanks for your response!
