[PATCH v3 0/5] hw/tpm: Remove instance @ppi_enabled field

[Philippe Mathieu-Daudé]

The "ppi" property and @ppi_enabled field were only used
for backward compatibility during the 3.1 release. We
removed all these legacy machines: the property isn't
required anymore. Still it was how the ACPI subsystem
was checking PPI use by TPM devices. This series convert
the per-instance field exposed as QOM property as a
single class (actually QOM interface) one.

[PATCH v3 2/5] hw/tpm: Add TPMIfClass::ppi_enabled field

[Philippe Mathieu-Daudé]

Each TMP derived device has a @ppi_enabled field, itself
exposed as a QOM property. External layers (like the ACPI
subsystem) wanting to know whether a device implements PPI
has to check for the QOM property available. This can be
simplified by declaring a single field in the TPM interface.

Here we add such field to TPMIfClass, before converting each
TPM devices to use it in the following commits.

[PATCH v3 3/5] hw/tpm: Remove CRBState::ppi_enabled field

[Philippe Mathieu-Daudé]

The CRBState::ppi_enabled boolean was only set in the
hw_compat_3_1[] array, via the 'ppi=false' property.
We removed all machines using that array, and the array
itself in commit a861ffef237 ("hw/core/machine: Remove
the hw_compat_3_1[] array"). We can safely remove the
now unused property. Since CRB devices always use PPI,
simplify removing the CRBState::ppi_enabled field.
Set the generic TPMIfClass::ppi_enabled so ACPI subsystem
can keep checking its availability.

[PATCH v3 4/5] hw/tpm: Propagate @ppi_enabled to tpm_tis_reset() and remove in TPMState

[Philippe Mathieu-Daudé]

Of TMP devices using FIFO mode, only the ISA variant has PPI,
and call tpm_ppi_init() to initialize the PPI state. Propagate
@ppi_enabled to tpm_tis_reset() so it only resets the PPI part
when requested (ISA case) otherwise the PPI is in uninitialized
state. Remove the now unused TPMState::ppi_enabled field. Set
the generic TPMIfClass::ppi_enabled so ACPI subsystem can keep
checking its availability.

Here's another TPM PPI related series. It would make sense to upstream 
them together. Do you want to queue that one as well?
