dbe63d3a27 - Bugfix: Fix a EHCI hardware race, where the hardware computed data toggle
value is updated after that we read it in the queue-head. This patch can
fix problems with BULK timeouts. The issue was found on a Nvidia chipset.

8833442863 Minor cleanup:
- use device_printf() instead of printf() to give more accurate warnings.
 - use memcpy() instead of bcopy().
 - add missing #if's for non-FreeBSD compilation.

6a9f4949fb Improve the error interrupt handler. In particular, read the
error address on a decoding error to unlatch it and to allow
us to print a better diagnostics message. This also has the
side effect of clearing the condition, which prevents an
interrupt storm.

c305730dc0 Remove bogus usage of INTR_FAST. "Fast" interrupts are now indicated by
registering a filter handler rather than a threaded handler.  Also remove

18ec652552 Adds a USB packet filter feature to the stack that it could capture
packets which go through each USB host controllers.  Its implementations
are almost based on BPF code and very similar with it except it's
little bit customized for USB packet only.  The userland program
usbdump(8) would be committed soon.

495ed64c16 The EHCI_CAPLENGTH and EHCI_HCIVERSION registers are actually sub-registers
within the first 4 bytes of the EHCI memory space. For controllers that
use big-endian MMIO, reading them with 1- and 2-byte reads would then
return the wrong values. Instead, read the combined register with a 4-byte
read and mask out the interesting quantities.

53e0bf6e70 Revert most of r197682 (EHCI Hardware BUG workaround). Implement
proper solution which is to not use the TERMINATE pointer, but rather
link to a halted TD. The initial fix was due to a misunderstanding
about how the EHCI hardware works. Thanks to Alan Stern for clearing
this up. This patch can increase mass storage read performance
significantly when the IRQ rate is less than 8000 IRQ/s.

963169b4af This commit adds full support for USB 3.0 devices in host and device
mode in the USB core.  The patch mostly consists of updating the USB
HUB code to support USB 3.0 HUBs. This patch also add some more USB
controller methods to support more active-alike USB controllers like
the XHCI which needs to be informed about various device state events.

USB 3.0 HUBs are not tested yet, due to lack of hardware, but are
believed to work.

After this update the initial device descriptor is only read twice
when we know that the bMaxPacketSize is too small for a single packet
transfer of this descriptor.

1354026034 Commit initial version of new XHCI driver which was written from
scratch. This driver adds support for USB3.0 devices. The XHCI
interface is also backwards compatible to USB2.0 and USB1.0 and will
evntually replace the OHCI/UHCI and EHCI drivers.

There will be follow-up commits during the coming week to link the
driver into the default kernel build and add missing USB3.0
functionality in the USB core. Currently only the driver files are
committed.

db5ef4fc77 Convert Marvell ARM platforms to FDT convention.
The following systems are involved:

  - DB-88F5182
  - DB-88F5281
  - DB-88F6281
  - DB-78100
  - SheevaPlug

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Marvell ARM SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
    good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

d1f7c4baa1 Back out r203140 which was causing problems when the first and the last
microframe slot was not in the smask. The problem was that the EHCI driver was
then thinking that the transfer was immediately complete in some cases. Which
could lead to freeze-like situations, which can be recovered by unplugging the
USB device.
