Got it working and posted a sepaate patch.  I will add documentation as well, but
here is what I ran. It should be similar to what I documented on the qemu wiki:

  https://wiki.qemu.org/Documentation/Platforms/OpenRISC

    $ /home/shorne/work/openrisc/qemu/build/or1k-softmmu/qemu-system-or1k -cpu or1200 \
      -M or1k-sim \
      -kernel /home/shorne/work/openrisc/barebox/barebox \
      -net nic -net tap,ifname=tap0,script=no,downscript=no \
      -serial mon:stdio -nographic \
      -gdb tcp::10001 \
      -m 32

    Board: or1ksim
    mdio_bus: miibus0: probed
