| # 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). |

| 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. |

| 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. |
