Usually we pass full console=ttySAC2,115200n8 from UBoot to command line. The usage of serial options allows skipping that. I can split the cleanup part from improvement. To me it looked a little bit too much but I don't mind. > I guess that prior to this patch Linux might change the rate of the > console, but otherwise it should work. It still can be overridden by command line if needed. Best regards, Krzysztof
