It has been only tested as console UART.
The tty name is ttyS based instead of ttyO. How big is the pain here,
what could be the easiest way to provide compatibility?

have been considering that myself for months. You could pass an optional
argument to serial8250_register_8250_port() but that only solves part of
the problem :-(

When ttyS -> ttyO change was done on OMAP, compatibility was not an issue.
Why should we care about it now?

It would be a good opportunity to force everyone to update their bootloader. ;)

Besides the BeagleBoard forum is quiet now, no one is complaining
about that old (ttyS -> ttyO) transition anymore..

I'll just end up carrying a patch like, to support bb.org users over
the transition..
