I dropped the bootargs but how do you see it here?

Of course I can do this, so that is what I did:

&uart0 {
    status = "okay";
    current-speed = <115200>;

But that only indicates that the hardware (firmware) set up the
port to a speed like that. It wouldn't work if the hardware was
set any other way. It seems to be like so on the PogoPlug though
so I went with this.

It has no way to indicate how parity etc was set up on the UART

However there is also stdout-path, so I went for this:

stdout-path = "serial0:115200n8";

Reposting the patch soon.
