ddaa454e6a Apply driver update from LSI. Many thanks to LSI for continuing to
support FreeBSD.

  1) Timeout ioctl command timeouts.
       Do not reset the controller if ioctl command completed
       successfully.
  2) Remove G66_WORKAROUND code (this bug never shipped).
  3) Remove unnecessary interrupt lock (intr_lock).
  4) Timeout firmware handshake for PChip reset (don't wait forever).
  5) Handle interrupts inline.
  6) Unmask command interrupt ONLY when adding a command to the pending
     queue.
  7) Mask command interrupt ONLY after removing the last command from
     the pending queue.
  8) Remove TW_OSLI_DEFERRED_INTR_USED code.
  9) Replace controller "state" with separate data fields to avoid races:

       TW_CLI_CTLR_STATE_ACTIVE                     ctlr->active
       TW_CLI_CTLR_STATE_INTR_ENABLED               ctlr->interrupts_enabled
       TW_CLI_CTLR_STATE_INTERNAL_REQ_BUSY          ctlr->internal_req_busy
       TW_CLI_CTLR_STATE_GET_MORE_AENS              ctlr->get_more_aens
       TW_CLI_CTLR_STATE_RESET_IN_PROGRESS          ctlr->reset_in_progress
       TW_CLI_CTLR_STATE_RESET_PHASE1_IN_PROGRESS   ctlr->reset_phase1_in_progress

 10) Fix "req" leak in twa_action() when simq is frozen and req is NOT
     null.
 11) Replace softc "state" with separate data fields to avoid races:
       TW_OSLI_CTLR_STATE_OPEN                      sc->open
       TW_OSLI_CTLR_STATE_SIMQ_FROZEN               sc->simq_frozen
 12) Fix reference to TW_OSLI_REQ_FLAGS_IN_PROGRESS in
     tw_osl_complete_passthru()
 13) Use correct CAM status values.
       Change CAM_REQ_CMP_ERR to CAM_REQ_INVALID.
       Remove use of CAM_RELEASE_SIMQ for physical data addresses.
 14) Do not freeze/ release the simq with non I/O commands.
       When it is appropriate to temporarily freeze the simq with an I/O
       command use:
         xpt_freeze_simq(sim, 1);
         ccb->ccb_h.status |= CAM_RELEASE_SIMQ;
       otherwise use:
         xpt_freeze_simq(sim, 1);
         xpt_release_simq(sim, 1);

4511a5c893 Import version 3.60.03.006 of the TWA driver:
This patch does the following:

- Remove un-necessary code that is not even compiling into the driver
 under TW_OSL_NON_DMA_MEM_ALLOC_PER_REQUEST defines.
- Remove bundled firmware image and associated "files" entry for tw_cl_fwimg.c
- Remove bundled firmware flashing routines. We now have tw_update userspace
 FreeBSD controller flash utility.
- Fix driver crash on load due to shared interrupt.
- Fix 2 lock leaks for Giant lock.
- Fix CCB leak.
- Add support for 9650SE controllers.

Many thanks to 3Ware/AMCC for continuing to support FreeBSD.

f0c1dee27f The latest release of the FreeBSD driver (twa) for
3ware's 9xxx series controllers.  This corresponds to
the 9.2 release (for FreeBSD 5.2.1) on the 3ware website.

Highlights of this release are:

1. The driver has been re-architected to use a "Common Layer"
    (all tw_cl* files), which is a consolidation of all OS-independent
    parts of the driver.  The FreeBSD OS specific portions of the
    driver go into an "OS Layer" (all tw_osl* files).
    This re-architecture is to achieve better maintainability, consistency
    of behavior across OS's, and better portability to new OS's (drivers
    for new OS's can be written by just adding an OS Layer that's specific
    to the OS, by complying to a "Common Layer Programming Interface" API.

2. The driver takes advantage of multiple processors.

3. The driver has a new firmware image bundled, the new features of which
   include Online Capacity Expansion and multi-lun support, among others.
   More details about 3ware's 9.2 release can be found here:
   http://www.3ware.com/download/Escalade9000Series/9.2/9.2_Release_Notes_Web.pdf

Since the Common Layer is used across OS's, the FreeBSD specific include
path for header files (/sys/dev/twa) is not part of the #include pre-processor
directive in any of the source files.  For being able to integrate twa into
the kernel despite this, Makefile.<arch> has been changed to add the include
path to CFLAGS.
