Thanks for your concern on this point. Actually speaking, I am a little puzzled toward the fact whether to disable serial console or not. Anyway,
As a developer of U-Boot, yo don't want to do that - you always want to have the most convenient access methods available :-)
But there are situation when the end user needs the serial port for other purposes, and U-Boot is prepared to deal wih this situation. If everything else fails you can use netconsole.
Does this make the difference? My hack method is to fix common/main.c to disable any serial input for my board. It worked but I couldn't switch to serial console anymore. So sadly...
No need to hack anything. All necessary defines to shut down the serial console completely are already in place. Just define them in your board config file.
