ba835e3fe6 Add code for ACPI PCI link object manipulation.
This allocate the best IRQ to boot-disable devices (have IRQ 0).
Allocated IRQ will be used for PCI interrupt routing when ACPI is
enabled.

Note that verbose messaging enabled for the time being so that
people can easily notice the strange behavior if it happened.

b8581e0d56 Now that we only probe host-PCI bridges once, we no longer have to check to
see if we have been probed before by checking for a pciX bus device.

2ccfc93222 Overhaul the ACPI PCI bridge driver a bit:
- Add an ACPI PCI-PCI bridge driver (the previous driver just handled
  Host-PCI bridges) that is a PCI driver that is a subclass of the generic
  PCI-PCI bridge driver.  It overrides probe, attach, read_ivar, and
  pci_route_interrupt.
  - The probe routine only succeeds if our parent is an ACPI PCI bus which
    we test for by seeing if we can read our ACPI_HANDLE as an ivar.
  - The attach routine saves a copy of our handle and calls the new
    acpi_pcib_attach_common() function described below.
  - The read_ivar routine handles normal PCI-PCI bridge ivars and adds an
    ivar to return the ACPI_HANDLE of the bus this bridge represents.
  - The route_interrupt routine fetches the _PRT (PCI Interrupt Routing
    Table) from the bridge device's softc and passes it off to
    acpi_pcib_route_interrupt() to route the interrupt.
- Split the old ACPI Host-PCI bridge driver into two pieces.  Part of
  the attach routine and most of the route_interrupt routine remain in
  acpi_pcib.c and are shared by both ACPI PCI bridge drivers.
  - The attach routine verifies the PCI bridge is present, reads in
    the _PRT for the bridge, and attaches the child PCI bus.
  - The route_interrupt routine uses the passed in _PRT to route a PCI
    interrupt.
  The rest of the driver is the ACPI Host-PCI bridge specific bits that
  live in acpi_pcib_acpi.c.
  - We no longer duplicate pcib_maxslots but use it directly.
  - The driver now uses the pcib devclass instead of its own devclass.
    This means that PCI busses are now only children of pcib devices.
  - Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar
    of the child bus.
  - Fetch the _PRT for routing PCI interrupts directly from our softc
    instead of walking the devclass to find ourself and then fetch our
    own softc.

With this change and the new ACPI PCI bus driver, ACPI can now properly
route interrupts for devices behind PCI-PCI bridges.  That is, the
Itanium2 with like 10 PCI busses can now boot ok and route all the PCI
interrupts.  Hopefully this will also fix problems people are having with
CardBus bridges behind PCI-PCI bridges not properly routing interrupts
when ACPI is used.

Tested on:	i386, ia64

473f1ca90d In acpi_pcib_route_interrupt(), the code claims to check to see if a PCI
LNK device (interrupt source provider sort of) is present before using it,
but the code actually tested the status (_STA) of the PCI bridge device
doing the routing, not the actual LNK device.  Fix it to check the status
of the LNK device.

43896e913a Update usage of AcpiEnableEvent to reflect a new argument.
Fix acpi_DeviceIsPresent to check for valid _STA data and to check
the "present" and "functioning" bits.

Use acpi_DeviceIsPresent in acpi_pcib rather than rolling our own
(also broken) version.

f16527bb44 The current resource buffer returned from an interrupt link device
in the case where there are no interrupts routed for it does not
contain enough space to use it to route an interrupt.  In the case
where we need to route an interrupt, throw away the returned buffer
and create a new one containing the interrupt we want.

4fa387b692 Implement PCI interrupt routing using the ACPI data attached to the
PCI bus object.  This should deal both with already-routed interrupts
as well as devices that need an interrupt routed.

Note that it *doesn't* deal with interlocked interrupt dependancies, nor
does it select between interrupt options in a smart way.  These are
optimisations that need further work.

91467fc61d ACPI_NUMBER becomes ACPI_INTEGER. acpi_EvaluateNumber becomes
acpi_EvaluateInteger.

Use acpi_EvaluateInteger instead of doing things the hard way where
possible.

AcpiSetSystemSleepState (unofficial) becomes AcpiEnterSleepState.

Use the AcpiGbl_FADT pointer rather than searching for the FADT.

39a8493ac0 Hack in interrupt routing support (using the core $PIR support, not using
ACPICA properly).  This makes it possible to use ACPICA in conjunction with
CardBus before I get around to implementing ACPI/PCI interrupt routing.

0ae554237c - Convert a lot of homebrew debugging output to use the ACPI CA debugging
infrastructure.  It's not perfect, but it's a lot better than what
   we've been using so far.  The following rules apply to this:
    o BSD component names should be capitalised
    o Layer names should be taken from the non-CA set for now.  We
      may elect to add some new BSD-specific layers later.

 - Make it possible to turn off selective debugging flags or layers
   by listing them in debug.acpi.layer or debug.acpi.level prefixed
   with !.

 - Fully implement support for avoiding nodes in the ACPI namespace.
   Nodes may be listed in the debug.acpi.avoid environment variable;
   these nodes and all their children will be ignored (although still
   scanned over) by ACPI functions which scan the namespace.  Multiple
   nodes can be specified, separated by whitespace.

 - Implement support for selectively disabling ACPI subsystem components
   via the debug.acpi.disable environment variable.  The following
   components can be disabled:
    o bus	creation/scanning of the ACPI 'bus'
    o children	attachment of children to the ACPI 'bus'
    o button	the acpi_button control-method button driver
    o ec	the acpi_ec embedded-controller driver
    o isa	acpi replacement of PnP BIOS for ISA device discovery
    o lid	the control-method lid switch driver
    o pci	pci root-bus discovery
    o processor CPU power/speed management
    o thermal	system temperature detection and control
    o timer	ACPI timecounter
   Multiple components may be disabled by specifying their name(s)
   separated by whitespace.

 - Add support for ioctl registration.  ACPI subsystem components may
   register ioctl handlers with the /dev/acpi generic ioctl handler,
   allowing us to avoid the need for a multitude of /dev/acpi* control
   devices, etc.

3cd59d7b9c Revert attach() back to the old behaviour of calling bus_generic_attach().
The new way doesn't seem to work reliably and was causing devices to not
be seen.

042283a67b Update to work with the new ACPI CA snapshot.
- Use ACPI_PHYSICAL_ADDRESS
 - RSDT -> XSDT
 - FACP -> FADT
 - No APIC table support
 - Don't install a global EC handler; this has bad side-effects
   (it invokes _REG in *all* EC spaces in the namespace!)
 - Check for PCI bus instances already existing before adding them

15e32d5d03 Initial FreeBSD OSPM (operating system power management) modules for
ACPICA.  Most of these are still works in progress.  Support exists for:

 - Fixed feature and control method power, lid and sleep buttons.
 - Detection of ISA PnP devices using ACPI namespace.
 - Detection of PCI root busses using ACPI namespace.
 - CPU throttling and sleep states (incomplete)
 - Thermal monitoring and cooling control (incomplete)
 - Interface to platform embedded controllers (mostly complete)
 - ACPI timer (incomplete)
 - Simple userland control of sleep states.
 - Shutdown and poweroff.
