- # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
- #
- # - Host systems (like PCs) need CONFIG_USB (with "A" jacks).

- # - Some systems have both kinds of controllers.

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