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

menuconfig USB_GADGET
bool "USB Gadget Support"
help
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.

int "Maximum VBUS Power usage (2-500 mA)"

help
Some devices need to draw power from USB when they are
configured, perhaps to operate circuitry or to recharge
batteries. This is in addition to any local power supply,
such as an AC adapter or batteries.
Enter the maximum power your device draws through USB, in
milliAmperes. The permitted range of values is 2 - 500 mA;
0 mA would be legal, but can make some hosts misbehave.
This value will be used except for system-specific gadget
drivers that have more specific information.

Creates an Ethernet network device through a USB peripheral
controller. This will create a network interface on both the device

other nework interface.
It will bind on the peripheral USB controller, ignoring the USB hosts
controllers in the system.

prompt "USB Ethernet Gadget Model"
default USB_ETH_RNDIS
help
There is several models (protocols) to implement Ethernet over USB
devices. The main ones are Microsoft's RNDIS and USB's CDC-Ethernet
(also called CDC-ECM). RNDIS is obviously compatible with Windows,
while CDC-ECM is not. Most other operating systems support both, so
if inter-operability is a concern, RNDIS is to be preferred.
config USB_ETH_CDC
bool "CDC-ECM Protocol"
help
CDC (Communications Device Class) is the standard for Ethernet over
USB devices. While there's several alternatives, the most widely used
protocol is ECM (Ethernet Control Model). However, compatibility with
Windows is not that great.
config USB_ETH_RNDIS
bool "RNDIS Protocol"
help
The RNDIS (Remote Network Driver Interface Specification) is a
Microsoft proprietary protocol to create an Ethernet device over USB.
Windows obviously supports it, as well as all the major operating
systems, so it's the best option for compatibility.
