This in my testing is not working unless i add console=ttySO,115200 to the 
bootargs I get nothing out at all on the serial port, though in u-boot it had 
stdin as serial and stdout as vga.  what are all the possible options and how 
should things just work? the current patch is not a regression for Fedora.  I 
want to make things just work for all.

We should patch all boards to be the same. but it needs to work.
