The eLBC only handles 32-bit physical address in systems with 36-bit physical. The previos generation of LBC handled 34-bit physical address in 36-bit systems. Added a new CONFIG option to convey the difference between the LBC and eLBC.
Also added defines for XAM bits used in LBC for the extended 34-bit support.
