From: Fabio Estevam <[email protected]> Configure the USB0 DWC3 controller for peripheral mode and enable the required USB gadget options to support the U-Boot 'ums' command on the ROC-RK3399-PC Plus.
The 'ums' command provides a convenient way to expose the on-board eMMC as a USB Mass Storage device to a host computer, simplifying development, image installation and recovery without requiring removable media or network access. Limit the controller to High-Speed operation by using the USB2 OTG PHY.
