For the upstream devicetrees we actually have the following:

    chosen {
        stdout-path = "serial0";
        bootargs = "earlycon console=ttyS0,115200";
    };

I can update /chosen to be the same here.

I'm not entirely sure, but I don't think their bootloaders do this. At least on the
XGS1250-12, which is one of the most recent devices, I can't find anything. Certainly
the u-boot variables don't have any values set for bootargs.

Best,
