I'm not familiar with what Yocto does, but at least for Freescale PPC
chips QEMU does not emulate enough of the hardware to run U-Boot (at
least, not without significant U-Boot hacking that I'm not aware of
anyone having done).  QEMU loads Linux directly.

I don't see mpc83xx support in QEMU at all.
