Virtio operates with physical addresses, while busdma is designed to
map these to produce bus addresses. On most supported platforms,
these two are interchangeable; on powerpc platforms, they are not.
When on powerpc, set an IOMMU of NULL, which causes the powerpc busdma
code to bypass the iommu mapping; this leaves us with the physical
buffer addresses which the virtio host expects to see.

Simply said, WDAT is an abstraction for the real WDT hardware. For
instance, to add a newer generation WDT to ichwd(4), one must know the
detailed hardware registers, etc..
With WDAT, the necessary IO accesses to operate the WDT are comprehensively
described in it and no hardware knowledge is required.
With this driver, the WDT on Advantech ARK-1124C, Dell R210 and Dell R240 are
detected and operated flawlessly.
* While R210 is also supported by ichwd(4), others are not supported yet.
The unfortunate thing is that not all systems have WDAT defined.

IFCAP2_XXX constants are integers, they do not need shift for the

shift. Add convenience macro IFCAP2_BIT() for consumers.

Prior to Conrad's changes to replace session integer IDs with a
pointer to the driver-specific state in commit 1b0909d51a, the
driver had to find the softc pointer from the adapter before it could
locate the ccr_session structure for a completed request. Since
Conrad's changes, the ccr_session pointer can now be obtained directly
from the crp. Add a backpoint from ccr_session back to ccr_softc and
use this in place of the ccr_softc member in cxgbe's struct adapter.

Historically the ACPI _HID for both the Arm PL011 and Generic UARTs
was ARMH0011. In the Arm Base Boot Requirements 2.0 the Generic UART
_HID is changed to ARMHB000. Use this new value in the PL011 driver
where we support both UART types.
This has been observed in some recent EDK2 builds.

In 0a9a4d2cd6 a check for OPT_ACPI was added to the hwpmc Makefile
to fix loading the module in a kernel where ACPI has been disabled.
This broke loading the module when ACPI was enabled in the build as
OPT_ACPI isn't a Makefile macro so was always disabled.
Move this check to the C files where the DEV_ACPI macro does exist.

The SCMI specification describes a set of standard interfaces for power,
performance and system management.
SCMI is extensible and provides interfaces to access functions which are
often implemented in firmwares in the System Control Processor (SCP).
This implements Shared Memory-based transfer, which is one of the ways on
how messages are exchanged between agents and the platform.
This includes a driver for ARM Message Handling Unit (MHU) Doorbell, which
is a mechanism that the caller can use to alert the callee of the presence
of a message.
The support implements clock management interface. For instance this allows
us to control HDMI pixel clock on ARM Morello Board.
Tested on ARM Morello Board.
