This series handles the 6xx family: 603, 604, G2, G2LE,

What about the e300 ? I guess it's only a 603 variant for QEMU.

MPC5xx and MPC8xx.

These are linux-user only, no MMU. I wonder if we shouldn't simply
drop support. At least we could remove POWERPC_MMU_MPC8xx.


There is a patch upfront to move them all into the same
POWERPC_EXCP_6xx, but otherwise the rest of the series is pretty much
the same as I have done for the other CPUs.

This was tested with the 604 only. But I'm not too worried because
these 32 bit CPUs are quite similar to one another.
