+         When loading U-Boot into RAM over USB protocols using tools such as
+         tegrarcm or L4T's exec-uboot.sh/tegraflash.py, Tegra's USB device
+         mode controller is initialized and enumerated by the host PC running
+         the tool. Unfortunately, these tools do not shut down the USB
+         controller before executing the downloaded code, and so the host PC
+         does not "de-enumerate" the USB device. This option shuts down the
+         USB controller when U-Boot boots to avoid leaving a stale USB device
+         present.
