Firmware can be reprogrammed on devices from Hitachi, HP, IBM, Plextor,
Quantum, and Seagate. At least one device from each manufacturer has
been tested with some version of this code, and it has been used to
update thousands of drives so far.
The man page suggests having a backup of the drive's data, and the
operation must be confirmed, either interactively or on the command
line. (This is the same as the confirmation on the format command.)
This work is largely derived from fwprog.c by Andre Albsmeier.

1: add 'const' to char * where needed;
2: mark unused variables with __unused;
3: remove double prototypes for mode_edit and mode_list.
4: moves the global variables 'bus', 'target', and 'lun' into
the main function and protect them with #ifndef MINIMALISTIC,
5: renames 3 variable in order not to shadow other things
index -> indx -- in modepage_dump since index is a function
from <strings.h.>
arglist -> arglst -- in the function parse_btl since arglist
is also a global variable
convertend -> convertend2 -- in the function editentry_set
since that name is used two times within the function.
6: cast 0xffffffff in the macro RESOLUTION_MAX(size) to (int)
since it is unsigned otherwise.

related patches. These include:
* Mode page editting can be scripted. This involves two
things: first, if stdin is not a tty, changes are read from
stdin rather than invoking $EDITOR. Second, and more
importantly, not all modepage entries must be included in the
change set. This means that camcontrol can now gracefully handle
more intrusive editting from the $EDITOR, including removal or
rearrangement of lines. It also means that you can do stuff
like:
# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
# newfs /dev/da3
# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
* Range-checking on user-supplied input values. modeedit.c now
uses the field width specifiers to determine the maximum
allowable value for a field. If the user enters a value larger
than the maximum, it clips the value to the max and warns the
user. This also involved patching cam_cmdparse.c to be more
consistent with regards to the "count" parameter to arg_put
(previously is was the length of strings and 1 for all integral
types). The cam_cdbparse(3) man page was also updated to reflect
the revised semantics.
* In the process, I removed the 64 entry limit on mode pages (not
that we were even close to hitting that limit). This was a nice
side-effect of the other changes.
* Technically, the new mode editting functionality allows editting
of character array entries in mode pages (type 'c' or 'z'),
however since buff_encode doesn't grok them it is currently
useless.
* Camcontrol gained two new options related to mode pages: -l and
-b. The former lists all available mode pages for a given
device. The latter forces mode page display in binary format
(the default when no mode page definition was found in
scsi_modes).
* Added support for mode page names to scsi_modes. Allows names to
be displayed alongside mode numbers in the mode page
listing. Updated scsi_modes to use the new functionality. This
also adds the semicolon into the scsi_modes syntax as an
optional mode page definition terminator. This is needed to name
pages without providing a page format definition.
* Updated scsi_all.h to include a structure describing mode page
headers.
* Added $FreeBSD$ line to scsi_modes.

do things like:
camcontrol tur da5
or
camcontrol tur 1:2:0
or
camcontrol tur 1:2
These changes are fully backwards compatible with the original device
specification syntax (-n dev -u unit), so it is possible to use either
method to specify a device now.
The device specification changes do not affect the rescan, reset or debug
commands, since by design, those commands work on a bus or bus:target:lun
basis only.
Also, shorten the default usage statement so that it fits in a 24 column
terminal. The full usage statement is still available by using the "help"
"-h" or "-?" arguments to camcontrol.
