I confirm that u-boot correctly deals with aliases and chosen/stdout-path. Using linear aliases and assigning stdout to serial1 works. I also confirm that having ttyPS1 without having ttyPS0 works (only tested with this patch applied). I questioned this earlier. So it seems that the need for reversing these aliases is less strong now. If I remember correctly, Jan Kiszka was also using reversed aliases, but I don't know why. Helmut
