When iicbus is attached as child of Designware I2C controller it scans all
ACPI nodes for "I2C Serial Bus Connection Resource Descriptor" described
in section 19.6.57 of ACPI specs.
If such a descriptor is found, I2C child is added to iicbus, it's I2C
address, IRQ resource and ACPI handle are added to ivars. Existing
ACPI bus-hosted child is deleted afterwards.
The driver also installs so called "I2C address space handler" which is
disabled by default as nontested.
Set hw.iicbus.enable_acpi_space_handler loader tunable to 1 to enable it.

Without this change, if an AIF interrupt comes at the same time a SYNC
command is finished, the SYNC interrupt will be lost. This happens because
all interrupt bits (bellbits) are cleared, but only one of them is handled.
Debugging shows that, (at least) when !sc->msi_enabled and (sc->flags &
AAC_FLAGS_SYNC_MODE) is true (sync mode), both bits may be set at the same
time.

As written, the condition of (cdb[0] != 0x28 || cdb[0] != 0x2A) will always
be true, since if it's one, it's obviously not the other. Reading the code,
the intent appears to be that it should only perform the operation if it's
neither, otherwise the conditional can be elided.
Found by clang 10.
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.
