That doesn't really sound possible to me with a single kernel binary.  If
I remember correctly, e300 is a 603e style CPU, and e500 is a BookE CPU.
They have totally different MMUs (among other things), which means you
would really need to separate kernel binaries to support that.

I'm not an Freescale core expert though, so I might be confused or don't
know of some way that would work.
