2 # USB Gadget support on a system involves
3 # (a) a peripheral controller, and
4 # (b) the gadget driver using it.
6 # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !!
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.
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).
17 bool "USB Gadget Support"
21 USB is a master/slave protocol, organized with one master
22 host (such as a PC) controlling up to 127 peripheral devices.
23 The USB hardware is asymmetric, which makes it easier to set up:
24 you can't connect a "to-the-host" connector to a peripheral.
26 U-Boot can run in the host, or in the peripheral. In both cases
27 you need a low level bus controller driver, and some software
28 talking to it. Peripheral controllers are often discrete silicon,
29 or are integrated with the CPU in a microcontroller. The more
30 familiar host side controllers have names like "EHCI", "OHCI",
31 or "UHCI", and are usually integrated into southbridges on PC
34 Enable this configuration option if you want to run U-Boot inside
35 a USB peripheral device. Configure one hardware driver for your
36 peripheral/device side bus controller, and a "gadget driver" for
37 your peripheral protocol.

233 There is several models (protocols) to implement Ethernet over USB
234 devices. The main ones are Microsoft's RNDIS and USB's CDC-Ethernet
235 (also called CDC-ECM). RNDIS is obviously compatible with Windows,
236 while CDC-ECM is not. Most other operating systems support both, so
237 if inter-operability is a concern, RNDIS is to be preferred.
240 bool "CDC-ECM Protocol"
242 CDC (Communications Device Class) is the standard for Ethernet over
243 USB devices. While there's several alternatives, the most widely used
244 protocol is ECM (Ethernet Control Model). However, compatibility with
245 Windows is not that great.
248 bool "RNDIS Protocol"
250 The RNDIS (Remote Network Driver Interface Specification) is a
