No Forth needed for that. The device tree is constucred in in 
openbios/arch/ppc/qemu/init.c::arch_of_init(). You can try to put a loop 
around cpu->initfn(cpu); in this function, you still have the number of 
CPUs in temp at that point so maybe something like:

for (int i = 0; i < temp; i++)
    cpu->initfn(cpu);

might work but I did not try it.
