QEMU 5.0 will support the PAPR vTPM device model for TPM 1.2 and TPM 2.0.
This series of patches enables vTPM 2.0 support for the IBM vTPM driver.

Regards,
   Stefan

- v6->v7:
  - reverted changes in 1/3 due to xtensa not supporting API call;
    removed Jarrko's Acked-by
  - Added Nayna's Acked-by adn Tested-by to all patches

- v5->v6:
  - Nits in commit texts

- v4->v5:
  - Added error path in case tpm2_get_cc_attrs_tbl() fails

- v3->v4:
  - Dropped patch 3; getting command code attributes table in IBM driver

- v2->v3:
  - Added fixes tag to patch 2/4; the race seems to have existed
    since the driver was first added
  - Renamed tpm2_init to tpm2_init_commands in 3/4

- v1->v2:
  - Addressed comments to v1; added patch 3 to handle case when
    TPM_OPS_AUTO_STARTUP is not set
