This patch enables 4GB 64bit memory space for PCIE_2A to have BAR allocations of 64bit pref mem needed on this Qdrive3 platform with dual SoCs for root port and switch NT-EP. Hence this ranges property is overridden in sa8540p-ride.dts only. Signed-off-by: Shazad Hussain --- This patch depends on below patch series for vreg_l11a.
