Hi All,

does anyone know of the USB 3.1 support status in mainline U-Boot? I've
only seen these related patches:

     usb: common: add define of usb_speed_string()

     There is only declaration of usb_speed_string(), but no definition,
     so add it to avoid build error when call it.

With no real functional changes. So has anyone already successfully
tested an USB 3.1 controller in recent U-Boot?

Thanks,
Stefan
