Add description for the SolidRun AM642 SoM, and HummingBoard-T evaluation board. The SoM features: - 1x cpsw ethernet with phy - 2x pru ethernet with phy - eMMC - spi flash (assembly option) Additionally microSD and usb-2.0 otg are included in the SoM description as they are supported boot sources for the SOC boot-rom. The Carrier provides: - 3x RJ45 connector - 2x M.2 connector - USB-2.0 Hub - USB-A Connector - LEDs - 2x CAN transceiver - 1x RS485 transceiver - sensors The M.2 connectors support either USB-3.1 or PCI-E depending on status of a mux. By default the mux is switched off.
