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"
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.
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
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.

48 hex "Vendor ID of the USB device"
49 default 0x1f3a if ARCH_SUNXI
52 Vendor ID of the USB device emulated, reported to the host device.

82 USB_GADGET to be enabled.

87 bool "DesignWare USB2.0 HS OTG controller 8-bit PHY bus width"

90 PHY interface width to 8 bits, rather than the default (16 bits).

102 int "Maximum VBUS Power usage (2-500 mA)"
106 Some devices need to draw power from USB when they are
107 configured, perhaps to operate circuitry or to recharge
108 batteries. This is in addition to any local power supply,
109 such as an AC adapter or batteries.
111 Enter the maximum power your device draws through USB, in
112 milliAmperes. The permitted range of values is 2 - 500 mA;
113 0 mA would be legal, but can make some hosts misbehave.
115 This value will be used except for system-specific gadget
116 drivers that have more specific information.

148 bool "USB Ethernet Gadget"
149 default y if ARCH_SUNXI && USB_MUSB_GADGET
151 Creates an Ethernet network device through a USB peripheral
152 controller. This will create a network interface on both the device
153 (U-Boot) and the host (remote device) that can be used just like any
154 other nework interface.
155 It will bind on the peripheral USB controller, ignoring the USB hosts
156 controllers in the system.
161 prompt "USB Ethernet Gadget Model"
162 default USB_ETH_RNDIS
164 There is several models (protocols) to implement Ethernet over USB
165 devices. The main ones are Microsoft's RNDIS and USB's CDC-Ethernet
166 (also called CDC-ECM). RNDIS is obviously compatible with Windows,
167 while CDC-ECM is not. Most other operating systems support both, so
168 if inter-operability is a concern, RNDIS is to be preferred.
171 bool "CDC-ECM Protocol"
173 CDC (Communications Device Class) is the standard for Ethernet over
174 USB devices. While there's several alternatives, the most widely used
175 protocol is ECM (Ethernet Control Model). However, compatibility with
176 Windows is not that great.
179 bool "RNDIS Protocol"
181 The RNDIS (Remote Network Driver Interface Specification) is a
182 Microsoft proprietary protocol to create an Ethernet device over USB.
183 Windows obviously supports it, as well as all the major operating
184 systems, so it's the best option for compatibility.
