We need to figure out what it means to add new qemu machines like this
to OE-Core. I'm not against it however I can't offer the Yocto Project's
resources to test them at this point as we're haven't budgeted for it.

The above patches make sense regardless so I've merged them except the
final two machine files. I'd like to hold off adding those until the
system builds and runs with our default kernel and qemu recipes.
Hopefully this lets you develop without having a huge queue of patches. 

In the meantime we need to figure out the resource concern for testing.
Is there a commercial interest in these new machines from anyone who
could perhaps help with the resource issue?

Cheers,

Richard
