Done, next bunch of code will be posted w/o debug output (see code 
below), I just thought it would help track down the issues.

Nice :)

I got an FDT generated and passed it in through U-Boot (see code below)

You're right, I turned on CONFIG_OF_LIBFDT in include/configs/EP88x.h.

Here's where I'm at now:
