Leandro Lupori d8c51c6f74 [aacraid] Port driver to big-endian 
Port aacraid driver to big-endian (BE) hosts.

The immediate goal of this change is to make it possible to use the
aacraid driver on PowerPC64 machines that have Adaptec Series 8 SAS
controllers.

Adapters supported by this driver expect FIB contents in little-endian
(LE) byte order. All FIBs have a fixed header part as well as a data
part that depends on the command being issued to the controller.

In this way, on BE hosts, the FIB header and all FIB data structures
used in aacraid.c and aacraid_cam.c need to be converted to LE before
being sent to the adapter and converted to BE when coming from it.

The functions to convert each struct are on aacraid_endian.c.
For little-endian (LE) targets, they are macros that expand
to nothing.
In some cases, when only a few fields of a large structure are used,
the fields are converted inline, by the code using them.

# NOTES -- Lines that can be cut/pasted into kernel and hints configs.

# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
# 'makeoptions', 'hints', etc. go into the kernel configuration that you
# run config(8) with.
#
# Lines that begin with 'hint.' are NOT for config(8), they go into your

# NOTES conventions and style guide:
#
# Large block comments should begin and end with a line containing only a
# comment character.
#
# To describe a particular object, a block comment (if it exists) should
# come first. Next should come device, options, and hints lines in that
# order. All device and option lines must be described by a comment that
# doesn't just expand the device or option name. Use only a concise
# comment on the same line if possible. Very detailed descriptions of
# devices and subsystems belong in man pages.
#
# A space followed by a tab separates 'options' from an option name. Two
# spaces followed by a tab separate 'device' from a device name. Comments
# after an option or device should use one space after the comment character.
# To comment out a negative option that disables code and thus should not be
# enabled for LINT builds, precede 'options' with "#!".
#
#
# This is the ``identification'' of the kernel. Usually this should
# be the same as the name of your kernel.

# The `maxusers' parameter controls the static sizing of a number of

# FreeBSD processes are subject to certain limits to their consumption

# KTRACE enables the system-call tracing facility ktrace(2). To be more

# SCSI DEVICES
# SCSI DEVICE CONFIGURATION
# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers. The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# It is possible to wire down your SCSI devices so that a given bus,
# target, and LUN always come on line as the same device unit. In
# earlier versions the unit numbers were assigned in the order that
# the devices were probed on the SCSI bus. This means that if you
# removed a disk drive, you may have had to rewrite your /etc/fstab
# file, and also that you had to be careful when adding a new disk
# as it may have been probed earlier and moved your device configuration
# around.
# This old behavior is maintained as the default behavior. The unit
# assignment begins with the first non-wired down unit for a device
# type. For example, if you wire a disk as "da3" then the first
# non-wired disk will be assigned da4.
# The syntax for wiring down devices is:
hint.scbus.0.at="ahc0"
hint.scbus.1.at="ahc1"
hint.scbus.1.bus="0"
hint.scbus.3.at="ahc2"
hint.scbus.3.bus="0"
hint.scbus.2.at="ahc2"
hint.scbus.2.bus="1"
hint.da.0.at="scbus0"
hint.da.0.target="0"
hint.da.0.unit="0"
hint.da.1.at="scbus3"
hint.da.1.target="1"
hint.da.2.at="scbus2"
hint.da.2.target="3"
hint.sa.1.at="scbus1"
hint.sa.1.target="6"
# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.
# All SCSI devices allocate as many units as are required.
# The ch driver drives SCSI Media Changer ("jukebox") devices.
#
# The da driver drives SCSI Direct Access ("disk") and Optical Media
# ("WORM") devices.
#
# The sa driver drives SCSI Sequential Access ("tape") devices.
#
# The cd driver drives SCSI Read Only Direct Access ("cd") devices.
#
# The ses driver drives SCSI Environment Services ("ses") and
# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices.
#
# The pt driver drives SCSI Processor devices.
#
# The sg driver provides a passthrough API that is compatible with the
# Linux SG driver. It will work in conjunction with the COMPAT_LINUX
# option to run linux SG apps. It can also stand on its own and provide
# source level API compatibility for porting apps to FreeBSD.
#
# Target Mode support is provided here but also requires that a SIM
# (SCSI Host Adapter Driver) provide support as well.
#
# The targ driver provides target mode support as a Processor type device.
# It exists to give the minimal context necessary to respond to Inquiry
# commands. There is a sample user application that shows how the rest
# of the command support might be done in /usr/share/examples/scsi_target.
#
# The targbh driver provides target mode support and exists to respond
# to incoming commands that do not otherwise have a logical unit assigned
# to them.
#
# The pass driver provides a passthrough API to access the CAM subsystem.
