Will do. I'm looking at the serial console code and I don't see a
difference between earlycon= vs console= handling. And I know that
earlycon= doesn't go through the driver core and isn't affected by any
of this. If you have additional pointers on where console= is parsed,
feel free to pass it on. I'll continue poking at this.
