When you do earlycon with DT, better use a 'stdout-path' property that points
to the device, and just put 'earlycon' without arguments on the command line.

Sure ! I tried that once (3.16) and even the dts patch got merged but had to be reverted out !

Let me see if that works again since serial land has seen some significant churn in recent times

Thx for pointing this out !
