But if you don't specify the baud rate in any way, it'll default to 9600 except on the EV-64260-BP. Also I don't like calling the standard serial console "debug". A standard computer running UNIX or a UNIX-like system must have a standard serial port as the console for root to do sysadmin work, not a PeeCee video/keyboard.

I'm simply asking to remove the line from arch/ppc/config.in that makes the EV-64260-BP port have a different default from the rest of Linux, which I claim is inappropriate. > Bootloaders should simply use the port as it was > configured by the boot rom. I'm not talking about any bootloader, I'm talking about the kernel (vmlinux). My bootloader (ppc-linux-boot) doesn't know anything about UARTs at all, it makes console user services calls to the firmware ROM to talk to the abstract console device.
