acd727e7cb acpi-dsdt: procedurally generate _PRT
This replaces the _PRT constant with a method that computes it.

The problem is that the DSDT+SSDT have grown from 2.0 to 2.1,
enough to cross the 8k barrier (we align the ACPI tables to 4k
before putting them in fw_cfg).  This causes problems with
migration and the pc-i440fx-2.0 machine type.

The solution to the problem is to hardcode 64k as the limit,
but this doesn't solve the bug with pc-i440fx-2.0.  The fix will be
for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the
ACPI tables.  First, however, we must make the actual AML
equal or smaller; to do this, rewrite _PRT in a way that saves
over 1k of bytecode.

8dcf525abc acpi-build: append description for non-hotplug
As reported in
http://article.gmane.org/gmane.comp.emulators.qemu/253987
Mac OSX actually requires describing all occupied slots
in ACPI - even if hotplug isn't enabled.

I didn't expect this so I dropped description of all
non hotpluggable slots from ACPI.
As a result: before
commit 99fd437dee (enable
hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:

Hardware -> PCI Cards:

  Card          Type                 Driver Installed  Slot
 *ethernet      Ethernet Controller  Yes               PCI Slot 2

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Slot                  PCI Slot 2

    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

After commit 99fd437dee, users get:

Hardware -> PCI Cards:

  This computer doesn't contain any PCI cards. If you installed PCI
  cards, make sure they're properly installed.

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.

To fix, append description for all occupied non hotpluggable PCI slots.

One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.

99fd437dee acpi-build: enable hotplug for PCI bridges
This enables support for device hotplug behind
pci bridges. Bridge devices themselves need
to be pre-configured on qemu command line.

Design:
    - at machine init time, assign "bsel" property to bridges with
      hotplug support
    - dynamically (At ACPI table read) generate ACPI code to handle
      hotplug events for each bridge with "bsel" property

Note: ACPI doesn't support adding or removing bridges by hotplug.
We detect and prevent removal of bridges by hotplug,
unless they were added by hotplug previously
(and so, are not described by ACPI).

15bce1b7c5 Add DSDT node for AppleSMC
AppleSMC (-device isa-applesmc) is required to boot OS X guests.
OS X expects a SMC node to be present in the ACPI DSDT. This patch
adds a SMC node to the DSDT, and dynamically patches the return value
of SMC._STA to either 0x0B if the chip is present, or otherwise to 0x00,
before booting the guest.

    After changing the parameter from `NotSerialized` to `Serialized`, the
    remark is indeed gone and there is no size change.

    The remark was added in ACPICA version 20130517 [1] and gives the
    following explanation.

            If a thread blocks within the method for any reason, and another thread
            enters the method, the method will fail because an attempt will be
            made to create the same (named) object twice.

            In this case, issue a remark that the method should be marked
            serialized. ACPICA BZ 909.

74523b8501 i386: add ACPI table files from seabios
This adds ASL code as well as scripts for processing it,
imported from seabios git tree
commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd

Will be used for runtime acpi table generation.

Note:
This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the
side of caution and include them.
