Is this a big secret or just skimpy Freescale documentation?
Try emailing:
     Ed.Nuckolls@freescale.com
This effort could help expand projects such as:
      http://sourceforge.net/projects/jtager/
for us embedded powerpc users!

For myself, right now I can't get much help from Abatron turning
on a new MPC5200 design. My approach: debugging modified u-boot code 
running out of RAM....lots of machine checks!
