Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c. It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code. The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync(). Previously this was done in a type specific
way. Now it is done in a generic way by recording the list of
virtuals in the map.

parent PCI bus and remove the home-grown version in this driver.

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);

Reenable 64-bit DMA for twa(4) controllers, but use a boundary of 4GB to
prevent individual transactions from crossing a 4GB address boundary. Due
to bus_size_t type limitations, the driver uses a 2GB boundary in PAE
kernels.

Minor update to version 3.70.03.007

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.

twa corresponding to the 9.3.0.1 release on the 3ware website. This driver has
support for the 9xxxSX controllers, along with the earlier 9xxxS series
controllers.

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.
