51	  Universal Serial Bus (USB) is a specification for a serial bus
52	  subsystem which offers higher speeds and more features than the
53	  traditional PC serial port.  The bus supplies power to peripherals
54	  and allows for hot swapping.  Up to 127 USB peripherals can be
55	  connected to a single USB host in a tree structure.
56	  
57	  The USB host is the root of the tree, the peripherals are the
58	  leaves and the inner nodes are special USB devices called hubs.
59	  Most PCs now have USB host ports, used to connect peripherals
60	  such as scanners, keyboards, mice, modems, cameras, disks,
61	  flash memory, network links, and printers to the PC.
62
63	  Say Y here if your computer has a host-side USB port and you want
64	  to use USB devices.  You then need to say Y to at least one of the
65	  Host Controller Driver (HCD) options below.  Choose a USB 1.1
66	  controller, such as "UHCI HCD support" or "OHCI HCD support",
67	  and "EHCI HCD (USB 2.0) support" except for older systems that
68	  do not have USB 2.0 support.  It doesn't normally hurt to select
69	  them all if you are not certain.
70
71	  If your system has a device-side USB port, used in the peripheral
72	  side of the USB protocol, see the "USB Gadget" framework instead.
73
74	  After choosing your HCD, then select drivers for the USB peripherals
75	  you'll be using.  You may want to check out the information provided
76	  in <file:Documentation/usb/> and especially the links given in
77	  <file:Documentation/usb/usb-help.rst>.
78
79	  To compile this driver as a module, choose M here: the
80	  module will be called usbcore.
81
82config USB_PCI
83	bool "PCI based USB host interface"
84	depends on PCI
85	default y
86	help
87	  Many embedded system SOCs (e.g. freescale T2080) have both
88	  PCI and USB modules with the USB module directly controlled by
89	  registers and having no relationship to the PCI module.
90
91	  If you have such a device you may say N here and PCI related code
92	  will not be built in the USB driver.
93
94config USB_PCI_AMD
95	bool "AMD PCI USB host support"
96	depends on USB_PCI && HAS_IOPORT
97	default X86 || MACH_LOONGSON64 || PPC_PASEMI
98	help
99	  Enable workarounds for USB implementation quirks in SB600/SB700/SB800
100	  and later south bridge implementations. These are common on x86 PCs
101	  with AMD CPUs but rarely used elsewhere, with the exception of a few
102	  powerpc and mips desktop machines.
