Do you really want the platform to be this specific?

Why make E500MC a config option, if it's so similar? This way you
can't make a kernel with SPE support that can boot on both e500{,v2}
and e500mc...

Isn't there quite a bit more needed than just enabling this config
option for SMP to work? I.e. why not save this for when the rest is
posted?
