Ah, but my system wouldn't run so I had to touch something, somewhere.

The problem is easy to explain: the MPC852T has only brgc3 and 4; it
also has only scc3 and 4. mpc8xx's serial.c hard codes assignment to
brgc1 and also wires brgc1 to the selected SCC; these commands won't
work for me. That's what I'm trying to "fix" or not fix, as the case may
be. My question was, should I just use ifdefs for my board there in that
file, or should I make something fancier?

Ben
