arcconf tool by Adaptec already seems to use for identifying the
Serial Number of the devices.
Some simple things (like FIB setup and bound checks) are retrieved
from the Adaptec's driver, but this implementation is quite different
because it does use the normal buffer dmat area for loading segments
and not a special one (like the Adaptec's one does).

128 FIBs first and allocated more later if necessary. Remove now unused
definitions from the header file[1].
- Force sequential bus scanning. It seems parallel scanning is in fact
slower and causes more harm than good[1]. Adjust a comment to reflect that.

that get truly stuck will still trigger the warning and the hardware
health check, just a little bit later.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.
For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.
Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

The default (64K) is too pessimistic for "new comm" hardware.
Also, this is bad because multiple controllers get limited by
the global tunable.

register instead of AAC_RX_FWSTATUS, as that is the way it's done in
Adaptec's vendor driver and in the Linux drivers. (The same applies
to aac_rkt_get_fwstatus as well.)
However, a concern has been raised about the compatibility of this
change and old hardware / firmware versions. In the absense of
specific information, revert to the original behaviour if the firmware
does not support the "New comm." interface. Users of old cards or
firmware haven't reported the problems that are potentially solved by
switching to OMR0.
[1] Add the support for the NARK controller which seems a variant of
the i960Rx.
[2] Split up memory regions and other resources in 2 different parts
as long as NARK uses them separately (it is not clear to me
why though as long as there are no more informations available
on this controller). Please note that in all the other cases,
the regions overlaps leaving the default behaviour for all the
other controllers.
[3] Implement a clock daemon responsible for maintain updated the
wall clock time of the controller (run any 30 minutes)*.

* Please note that originally, in the Adaptec driver, the clock daemon
is not implemented with callouts as in our in-tree driver.

to trip a bug causing the latter to return a zeroed struct
aac_adapter_info. This causes two issues. One is cosmetic only --
a verbose boot prints information about the controller, and shows all
zero:
aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution),
unknown battery platform
The second problem is that the firmware version information is stored
away for aac_rev_check, for userland tools (like aaccli) to query via
the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls.
When aaccli encounters this issue it prints
Command Error: <The current AFAAPI.DLL is too old to work with the
current controller software.>
Move the RequestSupplementAdapterInfo call after RequestAdapterInfo,
which seems to fix both problems.
- Resource allocation in aac_alloc (moved from from aac_init)
- Interrupt setup in aac_setup_intr (from aac_attach)
- Container probing in aac_get_container_info (from aac_startup and
aac_handle_aif)
- Firmware status check moved to aac_check_firmware from aac_init
putting the correct size in the fib header. Presumably the older firmware
silently ignored a bad size field.
(This change tested with a 3805 controller. Passthrough devices were
created when running firmware build 12814, but not 15323 or later. With
this change they're created for both old and new firmware versions.)

FSACTL_LNX_SEND_LARGE_FIB, and FSACTL_LNX_SEND_RAW_SRB, and correct size

Adaptec's driver build 15317. Adaptec's commandline RAID tool arcconf uses
these ioctls when creating a RAID-10 array (and probably other operations
too).
