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. Configure one hardware driver for your 34 peripheral/device side bus controller, and a "gadget driver" for 35 your peripheral protocol. 36 37if USB_GADGET 38 39config USB_GADGET_ATMEL_USBA 40 bool "Atmel USBA" 41 select USB_GADGET_DUALSPEED 42 help 43 USBA is the integrated high-speed USB Device controller on 44 the AT32AP700x, some AT91SAM9 and AT91CAP9 processors from Atmel. 45 46config USB_GADGET_DWC2_OTG 47 bool "DesignWare USB2.0 HS OTG controller (gadget mode)" 48 select USB_GADGET_DUALSPEED 49 help 50 The Designware USB2.0 high-speed gadget controller 51 integrated into many SoCs.
