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.
