wii: Restrict IOP access to shared peripherals.

Ensure that the IOP cannot access peripherals by clearing the appropriate
bus access bit. I have observed OHCI reporting completion for TDs living
in ARM reserved memory at runtime, this seems to suppress that.

ohci: Allocate a whole cacheline for all descriptors

Allocate a whole cacheline for all descriptor types such that:
 i) they can be alloc'ed without USBMALLOC_COHERENT which can mean they're
    now mapped cacheable, and
ii) the "soft" versions are cacheable, and mapped as small as possible.

Patch/idea mainly from Nick (skrll@) with a few fixes from me.

wii: Enable ohci(4) driver.
This seems to be stable now, let's enable support for plugging in LS/FS
devices directly into the system without a hub.

Convert ohcireg.h to __BITS.  NFCI.

Merge netbsd-7-nhusb:
- API / infrastructure changes to support memory management changes.
- Memory management improvements and bug fixes.
- HCDs should now be MP safe
- conversion to KERNHIST based debug
- FS/LS isoc support on ehci(4).
- conversion to kmem(9)
- Some USB 3 support - mostly from Takahiro HAYASHI (t-hash).
- interrupt transfers now get proper DMA operations
- general bug fixes
     - kern/48308
     - uhub status notification improvements
     - umass(4) probe fix (applied to HEAD already)
     - ohci(4) short transfer fix
- Change the SOFTINT level from NET to SERIAL for the USB softint handler.
  This gives the callback a chance of running when another softint handler
  at SOFTINT_NET has blocked holding a lock, e.g. softnet_lock and most of
  the network stack.
     - kern/49065 - ifconfig tun0 ... sequence locks up system / lockup:
       softnet_lock held across usb xfr
     - kern/50491 - unkillable wait in usbd_transfer while using usmsc0
       on raspberry pi 2
     - kern/51395 - USB Ethernet makes xhci hang
- Various improvements to slhci(4)
- Various improvements to dwc2(4)

First pass at netbsd-7 updated with USB code from HEAD

Overhaul of USB stack, mostly DMA related

This applies to NetBSD 4.99.13 (March 1, 2007)

usbdi(9) interface is based on FreeBSD version, excluding
 - removal of portability code

Patch most NetBSD changes, excluding
 - DMA memory "reserve", since we don't need contiguous buffers any longer
 - volatiles in DMA structure, since it should not be needed
   with proper bus_dmamap_sync(9)s

DMA/non-DMA memory management overhaul
 - Move all DMA related code to usb_mem.[ch]
   (add usb_alloc_buffer_dma(), usb_free_buffer_dma(), etc.).
   XXX Should usb_mem.[ch] be renamed as usb_mem_dma.[ch] ?
 - Add corresponding non-DMA code to usb_mem_nodma.[ch] .
   Currently just use malloc(9).
 - Above files are conditionally used by config framework (added
   attributes to conf/files and dev/usb/files.usb).
 - Add diagnostic panics when resource allocation is requested
   on interrupt context.
 - Change memory allocations (that require context) from NOWAIT to WAITOK.

Allocate DMA/non-DMA buffer per host interface, not globally.
 advantage:	Buffers can be freed on detaching host interface.
		Activity of a host interface does not affect others.
 disadvantages:	It possibly consumes more memory.

API changes
 - usbd_alloc_xfer() is changed:
    old: usbd_xfer_handle usbd_alloc_xfer(usbd_device_handle dev);
    new: usbd_xfer_handle usbd_alloc_xfer(usbd_device_handle dev,
		usbd_pipe_handle pipe);
 - pipe argument of usbd_setup_*xfer() are now unused
   XXX the pipe argument should be removed?
 - add mapping APIs
 - async request will be processed as a task (kernel thread context),
   and delayed to some extent
 - usbdivar.h: struct usbd_xfer: renamed a member "allocbuf" to "hcbuffer"
   (mapped/allocated/refered buffer for HCI driver)
 - usb_port.h: change usb_proc_ptr from  struct ptoc *  to struct lwp *
 - usb_port.h: add usb_sigproc_ptr for psignal(9) (struct proc *)
 - usb.h: add UE_MAXPKTSZ(ep) and UE_MAXPKTSZ_MASK macros for USB 2.0

changes to USB device drivers
 - atu, aue, axe, cdce, cue, kue, rum, udav, upl, ural, url,
   uaudio, ubt, ucom, ugen, uhidev, uirda, ulpt, umidi, urio,
   uscanner, ustir, utoppy:
    * catch up API change of usbd_alloc_xfer()
 - umass, usscanner:
    * catch up API change of usbd_alloc_xfer()
    * eliminate memory copy for large transfer

ohci
 - free resources on detach
 - add lots of bus_dmamap_sync() operations
 - simplify the code of loading std chain
 - rewrite code of looking up TD/ITD from DMA addr by using allocation chunk
 - add workaround for CMD Tech 670 and 673 chipsets
 - make sure resources are not allocated in interrupt context
 - add support for mapping buffer and mbuf

slhci
 - allocate xfer and slhci_xfer at once, and simplify relevant code
 - add slhci_detach()
 - remove second arg of slhci_attach() since it is the same as the first arg.
 - add support for "mapping" (no, it doesn't map since it doesn't do DMA)
   buffer and mbuf
 - add pcmcia frontend
 - NOT TESTED, missing hardware

ehci
 - add lots of bus_dmamap_sync() operations, possibly too many
 - make sure resources are not allocated in interrupt context
 - add support for mapping buffer and mbuf
 - done only simple test

uhci
 - add lots of bus_dmamap_sync() operations, possibly too many
 - make sure resources are not allocated in interrupt context
 - add support for mapping buffer and mbuf

To do
 - review, test, debug
 - rewrite network drivers to utilize usbd_map_buffer_mbuf()
 - rewrite uaudio(4) to eliminate memcpy
 - "pipe" argument of usbd_setup_*xfer() should eventually be removed

sync with head.

Sync with head.

sync with head

Add the 'volatile' qualifier to all descriptor fields to prevent the
compiler optimising away or reordering accesses to them.

Fixes ehci(4) on NetBSD/evbarm when using -Os optimisation. It's likely
ohci(4) and uhci(4) are similarly afflicted, so the same changes have
been made there.

Quite how other platforms got away without this for so long is a mystery...

merge ktrace-lwp.

Sync with HEAD. Here we go again...

sync with -current

Correct status value check for OHCI isoc transfer;
the spec says that "not accessed" is 111x, not 1111.

Get rid of trailing white space.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Change my email address.

Add a delay before reading the number of ports from the controller to
avoid getting 0 from it.

A first stab at support for isochronous transfers.

Make control transfer of over 8K possible by using a chain of TDs.

Rename TAILMASK to HEADMASK, since it really masks the head pointer.
From FreeBSD.

Fiddle with over-current protect when turning on port power to make
things work for some OHCI controllers.

Fix typo in tailp bit defines.  From Nick Hibma.

Add framework for doing isoc transfers.  The actual scheduling code
is still missing.

Pull up to last week's -current.

Cosmetic changes and some small improvements.  From FreeBSD and Nick Hibma.

Handle the case when a USB transfer is so long that it crosses two page
(4K) boundaries.  OHCI cannot do that with a single TD so we make a chain.

Merge the soft_{td,ed} with the real {td,ed}.  This saves time and space.
(And fix typo in corresponding uhci change.)

Take care of some lines > 80 chars.

Make the copyright header conform to the NetBSD template.

Make sure the Endpoint Descriptor gets the correct maximum packet size.

And fix pastos.

Fix tyop.

Use PCI class/subclass/interface to match USB host controllers instead
of vendor/product id.  This makes the probe find more controllers
without recompilation.

Add USB support.  Supported so far:
* UHCI and OHCI host controllers on PCI
* Hubs
* HID devices withe special drivers for mouse and keyboard
* Printers
