+USB Gadget autostart Support
+----------------------------
+
+Barebox can be configured to start usbgadget automatically by using global variables,
+instead of creating boot script. This can be useful if autostart policy should be
+chosen at boot time from other driver or script.
+To get usbgadget autostart support barebox has to be compiled with
+CONFIG_USB_GADGET_AUTOSTART enabled.
+
+USB Gadget autostart Options
