Please add something after post to strip simple-bus off of the localbus
node's compatible.  Either you have board-control@0,0, or you have the
other stuff (did you ever find out what the situation with NAND is?) --
not both at the same time.  Or do you have U-Boot patching in status
updates now?

I realize this isn't a 32-bit versus 36-bit issue, but this seemed as
good a time as any to repeat this complaint. :-)
