CONFIG_EARLY_PRINTK=<INC>,<BASE_ADDRESS>,<OTHER_OPTIONS>
If <BAUD_RATE> is not given then the code will not try to
initialize the UART, so that bootloader or firmware settings can
be used for maximum compatibility.
+ - scif,<BASE_ADDRESS>,<VERSION>
+ - <VERSION> is a option to choose which interface version should
be used
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.
My point was not adding new alias (I am not in favor anyway), but giving
hint to the user how infer the value of <VERSION>.
The wiki page for the board can then explain a bit more into details how
to setup earlyprintk.
Cheers,
