Indeed, this is shorter way of specifying the default console by referring to uart device.

Really - I'm confused. When I last tried this for arc_uart (in 3.17 time frame), it would setup default console, but to use it for earlycon we needed bootargs=earlycon in chosen. However I had to revet that change since OF core still was fixing a few things in that area.
See mainline 22524b02b17b901f28 ("Revert "ARC: [arcfpga] stdout-path now suffices for earlycon/console"")
