	help
	  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.

config CMD_ENTERRCM
	bool "Enable 'enterrcm' command"
	default y
	help
	  Tegra's boot ROM supports a mode whereby code may be downloaded and
	  flash-programmed over a USB connection. On dev boards, this is
	  typically entered by holding down a "force recovery" button and
	  resetting the CPU. However, not all boards have such a button (one
	  example is the Compulab Trimslice), so a method to enter RCM from
	  software is useful.

	  Even on boards other than Trimslice, controlling this over a UART
	  may be useful, e.g. to allow simple remote control without the need
	  for mechanical button actuators, or hooking up relays/... to the
	  button.
