	  This option allows you to use a so-called USB EHCI Debug device

	  Linux "EHCI Debug Device gadget" driver found in recent kernel)
	  to retrieve the coreboot debug messages (instead, or in addition
	  to, a serial port).

	  This feature is NOT supported on all chipsets in coreboot!

	  It also requires a USB2 controller which supports the EHCI
	  Debug Port capability.

	  See http://www.coreboot.org/EHCI_Debug_Port for an up-to-date list
	  of supported controllers.

	  Selects which physical USB port usbdebug dongle is connected to.
	  Setting of 0 means to scan possible ports starting from 1.

	  Intel platforms have hardwired the debug port location and this
	  setting makes no difference there.

	  Hence, if you select the correct port here, you can speed up
	  your boot time. Which USB port number refers to which actual
	  port on your mainboard (potentially also USB pin headers on
	  your mainboard) is highly board-specific, and you'll likely
	  have to find out by trial-and-error.
