This "u132-hcd" module is one half of the "driver" for
ELAN's U132 which is a USB to CardBus OHCI controller
adapter. This module needs the "ftdi-elan" module in
order to communicate to CardBus OHCI controller inserted
into the U132 adapter.
When the "ftdi-elan" module detects a supported CardBus
OHCI controller in the U132 adapter it loads this "u132-hcd"
module.
Upon a successful device probe() the single workqueue
is started up which does all the processing of commands
from the USB core that implement the host controller.
The workqueue maintains the urb queues and issues commands
via the functions exported by the "ftdi-elan" module. Each
such command will result in a callback.
Note that the "ftdi-elan" module is a USB client driver.
Note that this "u132-hcd" module is a (cut-down OHCI)
host controller.
Thus we have a topology with the parent of a host controller
being a USB client! This really stresses the USB subsystem
semaphore/mutex handling in the module removal.

This modifies the HCD builds to automatically "-DDEBUG" if
CONFIG_USB_DEBUG is selected. It's just a minor source code cleanup,
guaranteeing consistency.

This moves the PCI quirk handling for USB host controllers from the
PCI directory to the USB directory. Follow-on patches will need to:
(a) merge these copies with the originals in the HCD reset methods.
they don't wholly agree, despite doing the very same thing; and
(b) eventually change it so "usb-handoff" is the default, to help
get more robust USB/BIOS/input/... interactions.

This patch provides an "isp116x-hcd" driver for Philips'
ISP1160/ISP1161 USB host controllers.
The driver:
- is relatively small, meant for use on embedded platforms.
- runs usbtests 1-14 without problems for days.
- has been in use by 6-7 different people on ARM and PPC platforms,
running a range of devices including USB hubs.
- supports suspend/resume of both the platform device and the root hub;
supports remote wakeup of the root hub (but NOT the platform device)
by USB devices.
- does NOT support ISO transfers (nobody has asked for them).
- is PIO-only.

This adds support for a CF-card USB Host adapter, the Ratoc REX-CFU1U, by
wrapping a PCMCIA driver around the existing "sl811-hcd" platform driver.
This CF card is especially useful for PDAs, which currently tend to have
no other solution for USB host capability.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
