In virtio_balloon_get_config() we initialize a struct virtio_balloon_config
which we then copy to guest memory. However, the local variable is not
zero initialized. This works OK at the moment because we initialize
all the fields in it; however an upcoming kernel header change will
add some new fields. If we don't zero out the whole struct then we
will start leaking a small amount of the contents of QEMU's stack
to the guest as soon as we update linux-headers/ to a set of headers
that includes the new fields.

Common function measurement block is used to report zPCI internal
counters of successful pcilg/stg/stb and rpcit instructions to
a memory location provided by the program.
This patch introduces a new ZpciFmb structure and schedules a timer
callback to copy the zPCI measures to the FMB in the guest memory
at an interval time set to 4s.
An error while attemping to update the FMB, would generate an error
event to the guest.
The pcilg/stg/stb and rpcit interception handlers increase the
related counter on a successful call.
The guest shall pass a null FMBA (FMB address) in the FIB (Function
Information Block) when it issues a Modify PCI Function Control
instruction to switch off FMB and stop the corresponding timer.

bridge is just a PCI device, we can simplify the code.
Notes: We cannot yet move the MSIX check or device ID creation +
zPCI device creation to the pre_plug handler as both parts are not
fixed before actual device realization (and therefore after pre_plug and
before plug). Once that part is factored out, we can move these parts to
the pre_plug handler, too and therefore remove all possible errors from
the plug handler.

Comit 2c28c49057 ("s390x/pci: let pci devices start in configured mode")
changed the initial state of zPCI devices from ZPCI_FS_STANDBY to
ZPCI_FS_DISABLED (a.k.a. configured). However we still only send a
HP_EVENT_RESERVED_TO_STANDBY event to the guest, indicating a wrong
state.
Let's send a HP_EVENT_TO_CONFIGURED event instead, to match the actual
state the device is in.
This fixes hotplugged devices having to be enabled explicitly in the
guest e.g. via echo 1 > /sys/bus/pci/slots/00000000/power.
On real HW, a PCI device always pops up in the STANDBY state. In QEMU,
we decided to let it show up directly in the configured state (as
configuring it is otherwise just an extra burden for the admin). We can
safely bypass the STANDBY state when hotplugging PCI devices to a guest.

The interface is described in the "TCG Platform Reset Attack
Mitigation Specification", chapter 6 "ACPI _DSM Function". According
to Laszlo, it's not so easy to implement in OVMF, he suggested to do
it in qemu instead.
See specification documentation for more details, and next commit for
memory clear on reset handling.
The underlying TCG specification is accessible from the following
page.

The TPM Physical Presence interface consists of an ACPI part, a shared
memory part, and code in the firmware. Users can send messages to the
firmware by writing a code into the shared memory through invoking the
ACPI code. When a reboot happens, the firmware looks for the code and
acts on it by sending sequences of commands to the TPM.
This patch adds the ACPI code. It is similar to the one in EDK2 but doesn't
assume that SMIs are necessary to use. It uses a similar datastructure for
the shared memory as EDK2 does so that EDK2 and SeaBIOS could both make use
of it. I extended the shared memory data structure with an array of 256
bytes, one for each code that could be implemented. The array contains
flags describing the individual codes. This decouples the ACPI implementation
from the firmware implementation.
The underlying TCG specification is accessible from the following page.

This patch implements version 1.30.

To avoid having to hard code the base address of the PPI virtual
memory device we introduce a fw_cfg file etc/tpm/config that holds the
base address of the PPI device, the version of the PPI interface and
the version of the attached TPM.

Implement a virtual memory device for the TPM Physical Presence interface.
The memory is located at 0xFED45000 and used by ACPI to send messages to the
firmware (BIOS) and by the firmware to provide parameters for each one of
the supported codes.
This interface should be used by all TPM devices on x86 and can be
added by calling tpm_ppi_init_io().
Note: bios_linker cannot be used to allocate the PPI memory region,
since the reserved memory should stay stable across reboots, and might
be needed before the ACPI tables are installed.
