I set the CPM BRG "clock-frequency = <153609>" (value obtained from
u-boot's 'brginfo' command), set my CPU "clock-frequency =
<100000000>" (down from 130000000) to match what u-boot is using, and
used the "console=ttyCPM0,9600n8" boot arg and I've finally got
console output! Thanks everyone!

I'll still try to figure out how to get u-boot to fill all this in.
