The Demo board is made by MediaTek and has a MT8195 SoC, associated with the MT6359 and MT6360 PMICs, and the MT7921 connectivity chip. The IOs available on that board are: * 1 USB Type-C connector with DP aux mode support * 1 USB Type-A connector * 1 full size HDMI RX and 1 full size HDMI TX connector * 1 uSD slot * 40 pins header * SPI interface header * 1 M.2 slot * 1 audio jack * 1 micro-USB port for serial debug * 2 connectors for DSI displays * 3 connectors for CSI cameras * 1 connector for a eDP panel * 1 MMC storage This commit adds basic support in order to be able to boot.
