pc_dimm_plug() has code that will be needed for memory plug handlers
in other archs too. Extract code from pc_dimm_plug() into a generic
routine pc_dimm_memory_plug() that resides in pc-dimm.c. Also
correspondingly refactor re-usable unplug code into pc_dimm_memory_unplug().

The section footer changes commit f68945d42bab ("Add a protective
section footer") and commit 37fb569c0198 ("Disable section footers
on older machine types") broke migration for any non-versioned
machines.
This pinpoints a problem of s390-ccw machines: it needs to
be versioned to be compatible with future changes in common
code data structures such as section footers.
Let's introduce a version scheme for s390-ccw-virtio machines.
We will use the old s390-ccw-virtio name as alias to the latest
version as all existing libvirt XML for the ccw type were expanded
by libvirt to that name.
The only downside of this patch is, that the old alias s390-ccw
will no longer be available as machines can have only one alias,
but it should not really matter.

commit fa92e218df1d ("s390x/ipl: avoid sign extension") introduced
a regression:
qemu-system-s390x -drive file=image.qcow,format=qcow2
does not boot, the bios states
"No virtio-blk device found!"
adding bootindex=1 does boot.
The reason is that the uint32_t as return value will not do the right
thing for the return -1 (default without bootindex).
The bios itself, will interpret a 64bit -1 as autodetect (but it will
interpret 32bit -1 as ccw device address ff.ff.ffff)

Handle the virtio-ccw revision according to what the guest sets.
When revision 1 is selected, we have a virtio-1 standard device
with byteswapping for the virtio rings.
When a channel gets disabled, we have to revert to the legacy behavior
in case the next user of the device does not negotiate the revision 1
anymore (e.g. the boot firmware uses revision 1, but the operating
system only uses the legacy mode).
Note that revisions > 0 are still disabled.

For a guest-initiated reset, we need to not only reset the virtio device,
but also reset the VirtioCcwDevice into a clean state. This includes
resetting the indicators, or else a guest will not be able to e.g.
switch from classic interrupts to adapter interrupts.
Split off this routine into a new function virtio_ccw_reset_virtio()
to make the distinction between resetting the virtio-related devices
and the base subchannel device clear.

Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.
This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.
Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
in use because it has been automatically connected to another device
(did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

If the user forgot if=none on their drive specification they're likely
to get an error message because the drive is assigned once automatically
by QEMU and once by the manual id=/drive= user command line specification.
Improve the error message produced in this case to explicitly guide the
user towards if=none.
We rephrase the "drive conflict but not for an if=something" error as
well to keep the wording in line.
The two cases that change are:
(1) Drive specified as to be auto-connected and also manually connected
(and the board does handle this if= type):
qemu-system-x86_64 -nodefaults -display none \
-drive if=scsi,file=tmp.qcow2,id=foo -device ide-hd,drive=foo
Previously:
qemu-system-x86_64: -device ide-hd,drive=foo: Property 'ide-hd.drive'
can't take value 'foo', it's in use
Now:
qemu-system-x86_64: -device ide-hd,drive=foo: Drive 'foo' is already in
use because it has been automatically connected to another device (did
you need 'if=none' in the drive options?)
(2) Drive specified to be manually connected in two different ways:
qemu-system-x86_64 -nodefaults -display none \
-drive if=none,file=tmp.qcow2,id=foo -device ide-hd,drive=foo \
-device ide-hd,drive=foo
Previously:

can't take value 'foo', it's in use

The BEV flag controls whether the boot exception vector is still
in place when starting a kernel. When cleared the exception vector
at EBASE (or hard coded address of 0x80000000) is used instead.
The early stages of the linux kernel would benefit from BEV still
being set to ensure any faults get handled by the boot rom exception
handlers. This is a moot point for system qemu as there aren't really
any BEV handlers, but there are other good reasons to change this...
The UHI (semi-hosting interface) defines special behaviours depending
on whether an application starts in an environment with BEV set or
cleared. When BEV is set then UHI assumes that a bootloader is
relatively dumb and has no advanced exception handling logic.
However, when BEV is cleared then UHI assumes that the bootloader
has the ability to handle UHI exceptions with its exception handlers
and will unwind and forward UHI SYSCALL exceptions to the exception
vector that was installed prior to running the application.

We have agreed that OpenFirmware device paths in the "bootorder" fw_cfg
file should follow the pattern
/pci@i0cf8,%x/...
for devices that live behind an extra root bus. The extra root bus in
question is the %x'th among the extra root buses. (In other words, %x
gives the position of the affected extra root bus relative to the other
extra root buses, in bus_nr order.) %x starts at 1, and is formatted in
hex.
The portion of the unit address that comes before the comma is dynamically
taken from the main host bridge, similarly to sysbus_get_fw_dev_path().

The sysbus_get_fw_dev_path() function formats OpenFirmware device path
nodes ("driver-name@unit-address") for sysbus devices. The first choice
for "unit-address" is the base address of the device's first MMIO region.
The second choice is its first IO port.
However, if two sysbus devices with the same "driver-name" lack both MMIO
and PIO resources, then there is no good way to distinguish them based on
their OFW nodes, because in this case unit-address is omitted completely
for both devices. An example is TYPE_PXB_HOST ("pxb-host").
For the sake of such devices, introduce the explicit_ofw_unit_address()
"virtual member function". With this function, each sysbus device in the
same SysBusDeviceClass can state its own address.

OVMF downloads the ACPI linker/loader script from QEMU when the edk2 PCI
Bus driver globally signals the firmware that PCI enumeration and resource
allocation have completed. At this point QEMU regenerates the ACPI payload
in an fw_cfg read callback, and this is when the PXB's _CRS gets
populated.
Unfortunately, when this happens, the PCI_COMMAND_MEMORY bit is clear in
the root bus's command register, *unlike* under SeaBIOS. The consequences
unfold as follows:
- When build_crs() fetches dev->io_regions[i].addr, it is all-bits-one,
because pci_update_mappings() --> pci_bar_address() calculated it as
PCI_BAR_UNMAPPED, due to the PCI_COMMAND_MEMORY bit being clear.
- Consequently, the SHPC MMIO BAR (bar 0) of the bridge is not added to
the _CRS, *despite* having been programmed in PCI config space.
- Similarly, the SHPC MMIO BAR of the PXB is not removed from the main
root bus's DWordMemory descriptor.
- Guest OSes (Linux and Windows alike) notice the pre-programmed SHPC BAR
within the PXB's config space, and notice that it conflicts with the
main root bus's memory resource descriptors. Linux reports
pci 0000:04:00.0: BAR 0: can't assign mem (size 0x100)
pci 0000:04:00.0: BAR 0: trying firmware assignment [mem
0x88200000-0x882000ff 64bit]
pci 0000:04:00.0: BAR 0: [mem 0x88200000-0x882000ff 64bit] conflicts
with PCI Bus 0000:00 [mem
0x88200000-0xfebfffff]
While Windows Server 2012 R2 reports
https://technet.microsoft.com/en-us/library/cc732199%28v=ws.10%29.aspx
This device cannot find enough free resources that it can use. If you
want to use this device, you will need to disable one of the other
devices on this system. (Code 12)
This issue was apparently encountered earlier, see the "hack" in:
https://lists.nongnu.org/archive/html/qemu-devel/2015-01/msg02983.html
and the current hole-punching logic in build_crs() and build_ssdt() is
probably supposed to remedy exactly that problem -- however, for OVMF they
don't work, because at the end of the PCI enumeration and resource
allocation, which cues the ACPI linker/loader client, the command register
is clear.
The "shpc" property of "pci-bridge", introduced in the previous patches,
allows us to disable the standard hotplug controller cleanly, eliminating
the SHPC bar and the conflict.

In the PCI expander bridge, we will want to disable those features of
pci-bridge that relate to SHPC (standard hotplug controller):
- SHPC bar and underlying MemoryRegion
- interrupt (INTx or MSI)
- effective hotplug callbacks
- other SHPC hooks (initialization, cleanup, migration etc)
Introduce a new feature request bit in the PCIBridgeDev.flags field, and
turn off the above if the bit is explicitly cleared.

When loading migration fails due to a disagreement about
PCI config data we don't currently get any errors explaining
that was the cause of the problem or which byte in the config
data was at fault.

This is done indirectly by adjusting two typedefs and helps emphasizing
that the respective tables aren't supposed to be modified at runtime
(as they may be shared between devices).

Functions setting errno commonly return just -1, which is of no
particular use in the log file.

Expecting the ROM BAR to be written with an all ones value when sizing
the region is wrong - the low bit has another meaning (enable/disable)
and bits 1..10 are reserved. The PCI spec also mandates writing all
ones to just the address portion of the register.
Use suitable constants also for initializing the ROM BAR register field

The code introduced to address XSA-126 allows simplification of other
code in xen_pt_initfn(): All we need to do is update "cmd" suitably,
as it'll be written back to the host register near the end of the
function anyway.
