I agree with Changming that we shouldn't setting PHYS_64BIT by default.  For the platforms covered by the mpc85xx_defconfig, most user won't need the PHYS_64BIT.  We shouldn't set the one with worse performance and unnecessary to most people as default.  Also all these platforms supports 32-bit mode.
