4	  Universal Serial Bus (USB) is a specification for a serial bus
5	  subsystem which offers higher speeds and more features than the
6	  traditional PC serial port.  The bus supplies power to peripherals
7	  and allows for hot swapping.  Up to 127 USB peripherals can be
8	  connected to a single USB host in a tree structure.
9
10	  The USB host is the root of the tree, the peripherals are the
11	  leaves and the inner nodes are special USB devices called hubs.
12	  Most PCs now have USB host ports, used to connect peripherals
13	  such as scanners, keyboards, mice, modems, cameras, disks,
14	  flash memory, network links, and printers to the PC.
15
16	  Say Y here if your device has an USB port, either host, peripheral or
17	  dual-role.
18
19	  For an USB host port, you then need to say Y to at least one of the
20	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
21	  controller, such as "UHCI HCD support" or "OHCI HCD support",
22	  and "EHCI HCD (USB 2.0) support" except for older systems that
23	  do not have USB 2.0 support.  It doesn't normally hurt to select
24	  them all if you are not certain.
25
26	  If your system has a device-side USB port, used in the peripheral
27	  side of the USB protocol, see the "USB Gadget" framework instead.
28
29	  After choosing your HCD, then select drivers for the USB peripherals
30	  you'll be using.  You may want to check out the information provided
31	  in <file:Documentation/usb/> and especially the links given in
32	  <file:Documentation/usb/usb-help.txt>.

40	  Enable driver model for USB. The USB interface is then implemented
41	  by the USB uclass. Multiple USB controllers of different types
42	  (XHCI, EHCI, OHCI) can be attached and used. The 'usb' command works
43	  as normal.
44
45	  Much of the code is shared but with this option enabled the USB
46	  uclass takes care of device enumeration. USB devices can be
47	  declared with the U_BOOT_USB_DEVICE() macro and will be
48	  automatically probed when found on the bus.
