Thank you for your suggestion, however that documentation does not answer
my questions I am afraid (and neither does serial-console.txt). Otherwise
I wouldn't have asked them in the first place. If you don't know the
answers either, then it's OK to say: "I don't know".

E.g. (given the parameter aliasing we have) will:

`earlycon=uart8250,io,0x3f8 console=tty0'
`console=tty0 earlycon=uart8250,io,0x3f8'

do what I expect it to, that is open the UART at 0x3f8 as an early console
and then hand it over to the ttyS0 device as respectively a secondary and
the primary (/dev/console) regular console? I've skipped options such as
baud rates for brevity.
