Not really, you can specify a different console device on the kernel command line at start-up.
(Kernel command line is usually defined in the U-Boot environment, so no code changes involved, just re-set what you need.)

This is part of the kernel, compiled in boot-flags. There's no u-boot env block data on the kpw. The uboot source doesn't clearly define that it looks for one either.

Not much time to work on this right now, but I REALLY want this also. Thanks for all the help so far!

Yes - you are looking at the hardcoded command line in the kernel build there.

But the one in the u-boot environment can over-ride it.
That one you are not seeing because it is in another part of the flash storage than that used for the user partitions.

Grab the datasheet on the flash chip for details of where/how to look if you want to see that area rather than just us u-boot commands to change it.

(To my eyes - the U-Boot source isn't clear about anything. )
