I don't know where these came from.  I guess someone modified misc.c?
I don't know what they indicate, either.

Don't messages like this get your attention?  Something is wrong with
the memory map, board information structure, or where you loaded the
software kernel and ram disk.

Really?  So, you modified arch/ppc/mbxboot/m8260_tty.c to use an SCC?
You have to make lots of changes to use SCC as a console.  I don't have
any board that uses the SCC for a serial port (easily, without some
hardware hacking), so I haven't tried this.

Not surprised if this is an SCC.  You have some work to contribute :-).
