Siflower SF19A2890 is an SoC with: Dual-core MIPS InterAptiv at 800MHz DDR3 controller One Gigabit Ethernet MAC with RGMII and IPv4 HNAT engine Built-in 2x2 11N + 2x2 11AC WiFi radio USB 2.0 OTG I2C/SPI/GPIO and various other peripherals This PR adds support for SF19A2890 EVB with ethernet support. EVB spec: Memory: DDR3 128M Ethernet: RTL8367RB 5-port gigabit switch Flash: 16M NOR Others: MicroUSB OTG, LED x 1, Reset button x1 The built image can be flashed using u-boot recovery. This target is marked as source-only until support for a commercial router board comes. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>
