Configurable region mask bits is needed for the Marvell Armada 7020/7040/8040 SOCs when the DT file places the PCIe window above the 4GB region. The Synopsis Designware PCIe IP in these SOCs is too old to specify the highest memory location supported by the PCIe, but practically supports such locations. Allow these locations to be specified in the DT file. First DT property is called num-dmamask, and can range between 33 and 64. Second DT property is called num-regionmask, and can range between 33 and 64.
