[PATCH 0/9] tpm: Enhance sandbox tpm2 emulation

[Simon Glass]

At present the TPM2 emulator lacks the ability to load and save the
state. This means it cannot be used for verify-boot flow that includes
multiple phases (e.g. VPL and SPL). It also lacks support for
non-volatile data storage.

This series adds these features to the TPM2 emulator, with some code
from TPM1 moving into a common file.

A few other clean-ups are included to make the two emulators more similar.


Simon Glass (9):
  sandbox: tpm: Split out common nvdata code
  sandbox: tpm: Tidy up reading and writing of device state
  sandbox: tpm: Support the define-space command
  sandbox: tpm: Correct handling of get-capability
  sandbox: tpm: Finish comments for struct sandbox_tpm2
  sandbox: tpm: Track whether the state is valid
  sandbox: tpm: Support nvdata in TPM2
  sandbox: tpm: Support storing device state in tpm2
  sandbox: tpm: Support extending a PCR multiple times
