Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
the informational print functions. Collapse the debug API a bit to be
more generic and not require as much code duplication. While here, fix
a bug in MPS that was already fixed in MPR.
All of the printing from the tables file now has wrappers so that the
handling is cleaner and it's possible to print something out (say, during
development) without having to fight the global debug flags. This re-org
will also make it easier to have the tables be compiled out at build time
if desired.
Other than fixing some minor bugs, there are no user-visible changes from
this change

Differential Revision: D9238
- remove special handling of zero length transfers in mpi_pre_fw_upload();
- add missing MPS_CM_FLAGS_DATAIN flag in mpi_pre_fw_upload();
- move mps_user_setup_request() call into proper place;
- increase user command timeout from 30 to 60 seconds;
- avoid NULL dereference panic in case of firmware crash.
Set max DMA segment size to 24bit, as MPI SGE supports it.
Use mps_add_dmaseg() to add empty SGE instead of custom code.
Tune endianness safety.

This involves significant changes to the mps(4) driver, but is not a
complete rewrite.
Some of the changes in this version of the driver:
- Integrated RAID (IR) support.
- Support for WarpDrive controllers.
- Support for SCSI protection information (EEDP).
- Support for TLR (Transport Level Retries), needed for tape drives.
- Improved error recovery code.
- ioctl interface compatible with LSI utilities.
mps.4: Update the mps(4) driver man page somewhat for the driver
changes. The list of supported hardware still needs to be
updated to reflect the full list of supported cards.
conf/files: Add the new driver files.
mps/mpi/*: Updated version of the MPI header files, with a BSD style
copyright.
mps/*: See above for a description of the new driver features.
modules/mps/Makefile:
Add the new mps(4) driver files.

Bring in a driver for the LSI Logic MPT2 6Gb SAS controllers.
This driver supports basic I/O, and works with SAS and SATA drives and
expanders.
Basic error recovery works (i.e. timeouts and aborts) as well.
Integrated RAID isn't supported yet, and there are some known bugs.
So this isn't ready for production use, but is certainly ready for
testing and additional development. For the moment, new commits to this
driver should go into the FreeBSD Perforce repository first
(//depot/projects/mps/...) and then get merged into -current once
they've been vetted.
This has only been added to the amd64 GENERIC, since that is the only
architecture I have tested this driver with.
