Just out of curiosity: What's the difference (if any) between -mcpu=e500mc64 
and -mcpu=e5500? AFAIK -mcpu=e500mc64 is supported by gcc since at least 
version 4.6 whereas -mcpu=e5500 is only supported since gcc 4.8. But is there 
actually any difference?

I had asked our compiler person that before sending...  the answer
wasn't very clear, but when I asked whether there was any benefit for
the kernel specifying e5500 (requiring an extra fallback check) he said
"probably not".  Eventually they'll probably just become aliases for the
same thing.  Currently they do have separate .md files though, so
they're not identical.
