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.
