Maybe we could try and keep (or rather make, s far as possible) lists sorted.

I think it is wrong to set both the SMC and the SCC "current-speed" to
the console baudrate. Only one port can be the current console, and
only for this one the value is correct.

Actually I wonder how this is supposed to work at all, as there are
two SMC and 4 SCC which all could be used as UART ports.

Isn't this calling for trouble?

Best regards,
