I assumed that because I've always needed a debugger when 
implementing kernel level components. Since you've implemented kernel 
level support for several 44x processors, I just assumed that you 
needed kdbg at some point. So you're saying that your additions 
worked right out of the gate and you never needed a debugger?  You're my hero!
