It integrates support for ethernet, USB, display (HDMI, DSI and LVDS), cameras (CSI-2 and GMSL), audio and various other peripherals. Add a .dts that models the SB-UCM. Not all peripherals present on the board are enabled yet, due to missing support in mainline, or just because I couldn't test them all. Missing features include PCIe, audio, camera, display, SIM and CAN. The I2C, SPI and other buses routed to extensions connectors have also not been tested. They can be added to the device tree at a later time.
