Add support for the SolidRun RZ/G2L SoM [1] on Hummingboard IIoT [2]. The SoM features: - 2x 1Gbps Ethernet with PHY - eMMC - 1/2GB DDR - WiFi + Bluetooth - SDHI Mux switching between eMMC and Carrier Board The HummingBoard IIoT features: - 3x USB-2.0 Type A connector - 2x 1Gbps RJ45 Ethernet - USB Type-C Console Port - microSD connector - RTC with backup battery - RGB Status LED - 1x M.2 B-Key connector with USB-2.0 + SIM card holder - 1x DSI Display Connector - GPIO header - 2x RS232/RS485 ports (configurable) - 2x CAN Descriptions for eMMC, microSD and RS485 are provided as overlays due to their dependency on configurable mux states.
