QorIQ SoCs (e5500 core, P5 family) have 2 BARs for local access windows, while MPC85XX, and P1/P2 families use only a single BAR register. This also adds the QORIQ_DPAA option, mutually exclusive to MPC85XX, to handle this difference. Obtained from: Semihalf Sponsored by: Alex Perez/Inertial Computing
