Add new driver for the TI AM65x SoC Gigabit Ethernet Switch subsystem (CPSW NUSS). It has two ports and provides Ethernet packet communication for the device and can be configured as an Ethernet switch. CPSW NUSS features: the Reduced Gigabit Media Independent Interface (RGMII), Reduced Media Independent Interface (RMII), and the Management Data Input/Output (MDIO) interface for physical layer device (PHY) management. The TI AM65x SoC has integrated two-port Gigabit Ethernet Switch subsystem into device MCU domain named MCU_CPSW0. One Ethernet port (port 1) with selectable RGMII and RMII interfaces and an internal Communications Port Programming Interface (CPPI) port (Host port 0).
Host Port 0 CPPI Packet Streaming Interface interface supports 8 TX channels and on RX channels operating by TI am654 NAVSS Unified DMA Peripheral Root Complex (UDMA-P) controller. The series is based on top of Vignesh's v3: https://patchwork.ozlabs.org/patch/1032504/ Tested for tftp and booting to kernel on am654-evm.
