1# 2# USB Gadget support on a system involves 3# (a) a peripheral controller, and 4# (b) the gadget driver using it. 5# 6# NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !! 7# 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. 11# 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). 14# 15 16menuconfig USB_GADGET 17 bool "USB Gadget Support" 18 help 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. 23 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 30 motherboards. 31 32 Enable this configuration option if you want to run U-Boot inside 33 a USB peripheral device.
