[PATCH v4 0/5] vTPM/aarch64 ACPI support

[Eric Auger <eric.auger@redhat.com>]

Those patches bring MMIO TPM TIS ACPI support in machvirt.
The TPM2 build function is converted to build_append style.
Then the code is moved to the generic part.

On ARM, the TPM2 table is added when the TPM TIS sysbus
device is dynamically instantiated in machvirt.

Also the TPM2 device object is described in the DSDT.

Many thanks to Ard for his support.

Tested with LUKS partition automatic decryption. Also
tested with new bios-tables-test dedicated tests,
sent separately.

Depends on "acpi: tpm: Do not build TCPA table for TPM 2"

Best Regards

Eric

- Restored tpm presence check in acpi_dsdt_add_tpm()
- add the doc related patch

v2 -> v3:
- Rebase on top of Stefan's
  "acpi: tpm: Do not build TCPA table for TPM 2"
- brings conversion to build_append

v1 -> v2:
- move build_tpm2() in the generic code (Michael)
- collect Stefan's R-b on 3/3
