We don't want PHYS_64BIT on unconditionally. It has the effect of moving all the devices into high physical memory, which means you need a different Linux/dts.
Another reason we should really be packaging the device trees with u-boot.
I expect the normal case to be that it is off. Just those few customers that actually want to do this will use the PHYS_64BIT version.
OK, though ideally it could be chosen dynamically based on how much memory there is (in u-boot) or #address-cells (in linux).
