The only use that I can see is if you specify `earlycon' without specifying `console' and then all you get are the initial kernel messages, after the serial drivers intializes all further messages go to the VGA. If makes much more sense to me to just use the `console' parameter to get all kernel messages on the serial port, and then there is no need for `earlycon'. -- Don Dugger "Censeo Toto nos in Kansa esse decisse." - D.
