Is that the right dts to use for a MPC8349SYS board?

I tried compiling it like this:

$ dtc -f -I dts -O dtb mpc8349emds.dts > devices.dtb
DTC: dts->dtb  on file "mpc8349emds.dts"
Warning: No cpu has "linux,boot-cpu" property
ERROR: Missing /chosen node
Input tree has errors

Is that really correct? Should I invoke dtc in some other way or modify
the dts or use some other dts file?

OK, I've adapted and applied those patches now. However, when I try to
boot with the dtd I generated above, then the kernel just hangs. For
now, I assume that is because of errors in the dtd and not in u-boot ...
