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.

|
|
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.

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.

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.
