The DW25GMAC introduced in this version adds new DMA architecture called Hyper-DMA (HDMA) for virtualization scalability. This is realized by decoupling physical DMA channels(PDMA) from potentially large number of virtual DMA channels (VDMA). The VDMAs are software abastractions that map to PDMAs for frame transmission and reception. To support the new HDMA architecture, a new instance of stmmac_dma_ops dw25gmac400_dma_ops is added. Most of the other dma operation functions in existing dwxgamc2_dma.c file are reused where applicable.
