Older DesignWare Ethernet MAC versions that this driver supports can only work with 32-bit DMA source/destination addresses. Some platforms have no physical RAM at the lowest 4GB address space. For these platforms the driver must translate DMA addresses to/from physical memory addresses.
Call translation routines so that properly configured platforms can use the DesignWare Ethernet MAC. For platforms using device-tree this usually means adding dma-ranges property to the bus the device node is in.
