From: Liming Wang <liming.wang@windriver.com>

With this new emulation, existing qemuppc functionality is maintained
and other functionality such as framebuffer + sato and NFS boot are
added.

We currently tune for 603e when we choose qemuppc machine is that still valid
core for G4 cpu ? I think from gcc point of view it should now use -m7400
so may be add another tune-file to oe-core

That was the plan, to fix the tuning of this and the other PPC reference boards
at the same time. Liming and I had discussed this before, and we wanted to get
this into the tree, and tweak it there.

Liming: we can open a bug to track the update of the tuning .. just so we don't
forget.

Cheers,

Bruce
