The issue is actually with serial-uclass.c when the kernel dts

Disabling uart0 (ie serial0) in u-boot.dtsi loses the console
instead of probing the pl01x for the platform_data.
is there a pre-defined way to work around this?
Provide a new stdout-path in the -u-boot.dtsi too? Any changes you
yes I obviously tried that but are you sure that that is allowed with
"chosen" it being kind of a special type of node?
the compiler just cant find the label when added to u-boot.dtsi hence
why I was asking (sorry, I should have raised it upfront)
ie:
/*

leads to

could make to the main dts file so that this would work should be able
to be done in the -u-boot.dtsi too.
