initialize the UART, so that bootloader or firmware settings can
be used for maximum compatibility.

By "a option" did you intend to mean it is an optional parameter?
If so, how about:
"SCIF<VERSION> is, optionally, the interface version of the UART."
agree. will change.
So you would also provide a way for the user to know how to specify
it. Stefano any opinion?
I am going to update Wiki page regarding how to run Stout board on Xen
and how to properly enable earlyprintk support on that board.
Would it be enough? Also I can add a note to patch description.
In V1 I added convenient alias EARLY_PRINTK_stout, but AFAIR it was
decided to avoid adding new aliases.
+ If <VERSION> is not given then a default interface version (SCIF)

ok
