   2 # USB Gadget support on a system involves
   3 #    (a) a peripheral controller, and
   4 #    (b) the gadget driver using it.
   5 #
   6 # NOTE:  Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
   7 #
   8 #  - Host systems (like PCs) need CONFIG_USB (with "A" jacks).
   9 #  - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks).
  10 #  - Some systems have both kinds of controllers.
  11 #
  12 # With help from a special transceiver and a "Mini-AB" jack, systems with
  13 # both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG).

  19            USB is a master/slave protocol, organized with one master
  20            host (such as a PC) controlling up to 127 peripheral devices.
  21            The USB hardware is asymmetric, which makes it easier to set up:
  22            you can't connect a "to-the-host" connector to a peripheral.
  23
  24            U-Boot can run in the host, or in the peripheral.  In both cases
  25            you need a low level bus controller driver, and some software
  26            talking to it.  Peripheral controllers are often discrete silicon,
  27            or are integrated with the CPU in a microcontroller.  The more
  28            familiar host side controllers have names like "EHCI", "OHCI",
  29            or "UHCI", and are usually integrated into southbridges on PC
  30            motherboards.
  31
  32            Enable this configuration option if you want to run U-Boot inside
  33            a USB peripheral device.  Configure one hardware driver for your
  34            peripheral/device side bus controller, and a "gadget driver" for
  35            your peripheral protocol.
