Checking  the source code seems to indicate that getspr 313 should
return it; on stock hostboot it pops out xome 0x8xxxx address. However I
can't get my cooked image to quiesce all the threads; ends up showing
threads 0-3 on core 3 being 'A' according to threadstatus... Is there a
'quiesce' opcode one can use, like the nap one?
