Niklas Schnelle 52e24f8c0a usb: pci-quirks: handle HAS_IOPORT dependency for AMD quirk 
In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. In the pci-quirks case the I/O port acceses are
used in the quirks for several AMD south bridges, Add a config option
for the AMD quirks to depend on HAS_IOPORT and #ifdef the quirk code.

config USB_ARCH_HAS_HCD def_bool y

config USB tristate "Support for Host-side USB" depends on USB_ARCH_HAS_HCD select GENERIC_ALLOCATOR select USB_COMMON select NLS # for UTF-8 strings help Universal Serial Bus (USB) is a specification for a serial bus subsystem which offers higher speeds and more features than the traditional PC serial port. The bus supplies power to peripherals and allows for hot swapping. Up to 127 USB peripherals can be connected to a single USB host in a tree structure.

  The USB host is the root of the tree, the peripherals are the
  leaves and the inner nodes are special USB devices called hubs.
  Most PCs now have USB host ports, used to connect peripherals
  such as scanners, keyboards, mice, modems, cameras, disks,
  flash memory, network links, and printers to the PC.

  Say Y here if your computer has a host-side USB port and you want
  to use USB devices.  You then need to say Y to at least one of the
  Host Controller Driver (HCD) options below.  Choose a USB 1.1
  controller, such as "UHCI HCD support" or "OHCI HCD support",
  and "EHCI HCD (USB 2.0) support" except for older systems that
  do not have USB 2.0 support.  It doesn't normally hurt to select
  them all if you are not certain.

  If your system has a device-side USB port, used in the peripheral
  side of the USB protocol, see the "USB Gadget" framework instead.

  After choosing your HCD, then select drivers for the USB peripherals
  you'll be using.  You may want to check out the information provided
  in <file:Documentation/usb/> and especially the links given in
  <file:Documentation/usb/usb-help.rst>.

  To compile this driver as a module, choose M here: the
  module will be called usbcore.

config USB_PCI bool "PCI based USB host interface" depends on PCI default y help Many embedded system SOCs (e.g. freescale T2080) have both PCI and USB modules with the USB module directly controlled by registers and having no relationship to the PCI module.

  If you have such a device you may say N here and PCI related code
  will not be built in the USB driver.

config USB_PCI_AMD bool "AMD PCI USB host support" depends on USB_PCI && HAS_IOPORT default X86 || MACH_LOONGSON64 || PPC_PASEMI help Enable workarounds for USB implementation quirks in SB600/SB700/SB800 and later south bridge implementations. These are common on x86 PCs with AMD CPUs but rarely used elsewhere, with the exception of a few powerpc and mips desktop machines.
