 * OHCI is the main "non-Intel/VIA" standard for USB 1.1 host controller
 * interfaces (though some non-x86 Intel chips use it).  It supports
 * smarter hardware than UHCI.  A download link for the spec available
 * through the http://www.usb.org website.
 *
- * History:
- * 
- * 2004/03/24 LH7A404 support (Durgesh Pattamatta & Marc Singer)
- * 2004/02/04 use generic dma_* functions instead of pci_* (dsaxena@plexity.net)
- * 2003/02/24 show registers in sysfs (Kevin Brosius)
- *
- * 2002/09/03 get rid of ed hashtables, rework periodic scheduling and
- *      bandwidth accounting; if debugging, show schedules in driverfs
- * 2002/07/19 fixes to management of ED and schedule state.
- * 2002/06/09 SA-1111 support (Christopher Hoover)
- * 2002/06/01 remember frame when HC won't see EDs any more; use that info
- *      to fix urb unlink races caused by interrupt latency assumptions;
- *      minor ED field and function naming updates
- * 2002/01/18 package as a patch for 2.5.3; this should match the
- *      2.4.17 kernel modulo some bugs being fixed.
- *
- * 2001/10/18 merge pmac cleanup (Benjamin Herrenschmidt) and bugfixes
- *      from post-2.4.5 patches.
- * 2001/09/20 URB_ZERO_PACKET support; hcca_dma portability, OPTi warning
- * 2001/09/07 match PCI PM changes, errnos from Linus' tree
- * 2001/05/05 fork 2.4.5 version into "hcd" framework, cleanup, simplify;
- *      pbook pci quirks gone (please fix pbook pci sw!) (db)
- *
- * 2001/04/08 Identify version on module load (gb)
- * 2001/03/24 td/ed hashing to remove bus_to_virt (Steve Longerbeam);
-        pci_map_single (db)
- * 2001/03/21 td and dev/ed allocation uses new pci_pool API (db)
- * 2001/03/07 hcca allocation uses pci_alloc_consistent (Steve Longerbeam)
- *
- * 2000/09/26 fixed races in removing the private portion of the urb
- * 2000/09/07 disable bulk and control lists when unlinking the last
- *      endpoint descriptor in order to avoid unrecoverable errors on
- *      the Lucent chips. (rwc@sgi)
- * 2000/08/29 use bandwidth claiming hooks (thanks Randy!), fix some
- *      urb unlink probs, indentation fixes
- * 2000/08/11 various oops fixes mostly affecting iso and cleanup from
- *      device unplugs.
- * 2000/06/28 use PCI hotplug framework, for better power management
- *      and for Cardbus support (David Brownell)
- * 2000/earlier:  fixes for NEC/Lucent chips; suspend/resume handling
- *      when the controller loses power; handle UE; cleanup; ...
- *
- * v5.2 1999/12/07 URB 3rd preview, 
- * v5.1 1999/11/30 URB 2nd preview, cpia, (usb-scsi)
- * v5.0 1999/11/22 URB Technical preview, Paul Mackerras powerbook susp/resume 
- *      i386: HUB, Keyboard, Mouse, Printer 
- *
- * v4.3 1999/10/27 multiple HCs, bulk_request
- * v4.2 1999/09/05 ISO API alpha, new dev alloc, neg Error-codes
- * v4.1 1999/08/27 Randy Dunlap's - ISO API first impl.
