I've taken a slightly different approach than is used with the ICH8 controllers
in that each controller is not identified individually (eg USB A, USB B, etc).
Instead I've given then same description to each one even though the device ID
differs. This can easily be changed if desired, or ICH8 (and any others using
that approach) can be made to work as this does.
o Consistently use device_foo_t and bus_foo_t for functions implementing
device_foo and bus_foo respectively. Adjust those routines that were wrong
(we should do this throughout the tree).
o make all the modules depend on usb. Otherwise these modules won't
load.
o ucycom doesn't need usb_port.h
o Minor unifdefing
o uhub, umass, ums, urio, uscanner conversion complete.
o ukbd: Remove the NO_SET_PROTO quirk (fixes a PR 77940). NetBSD removed
their check and setting the proto a long time ago.
o umodem panic fixed. UQ_ASSUME_CM_OVER_DATA quirk removed because I've never
seen a umodem that needed this rejection for proection (this gets rid of
~20% of the quirks).

sparc64 GENERIC and the sound device drivers known working on sparc64
to use bus_get_dma_tag() to obtain the parent DMA tag so we can get rid
of the sparc64_root_dma_tag kludge eventually. Except for ath(4), sk(4),
stge(4) and ti(4) these changes are runtime tested (unless I booted up
the wrong kernels again...).
host controllers to avoid the need to allocate any multi-page
physically contiguous memory blocks. This makes it possible to use
USB devices reliably on low-memory systems or when memory is too
fragmented for contiguous allocations to succeed.
The USB subsystem now uses bus_dmamap_load() directly on the buffers
supplied by USB peripheral drivers, so this also avoids having to
copy data back and forth before and after transfers. The ehci and
ohci controllers support scatter/gather as long as the buffer is
contiguous in the virtual address space. For uhci the hardware
cannot handle a physical address discontinuity within a USB packet,
so it is necessary to copy small memory fragments at times.
rather than a softc pointer (with the bus structure at the start).
This is a non-functional change. It just helps when reading the code to
know that the ehci, ohci and uhci drivers share the bus structure, not the
entire softc.
this problem put these lines back in. While they should be
unnecessary, they appear to be sometimes necessary.

Reading the PCI config space with the wrong (larger) size is not
a problem in this case, but writing can be as it clobbers unrelated
registers. In this case the clobbering is for reserved fields, which
too is mostly harmless... for now. Hence, this change is mostly
preventive in nature.

patch, I can now boot with PNP-OS YES in my BIOS no differently than

I'm not sure BUF_KERNPROC() is even the right thing to do or in the
right place or implemented the right way (inline vs normal function).
Remove consequently unneeded #includes of <sys/proc.h>

This fixes the problem of uhub0 hanging forever during boot when USB

device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

by identifying the version in the PCI drivers.
The OHCI driver just presets this to 1.0 as it is not specified in the
PCI registers anywhere. This should be revisited once USB 2.0 is in
wide spread use.
