The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are similar to the R-Car Ethernet AVB IP. The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller (DMAC). With a few changes in the driver we can support both IPs. This patch series is aims to add functional support for Gigabit Ethernet driver by filling all the stubs.
