 Currently this repository provides two TCTI implementations: libtss2-tcti-device and libtss2-tcti-mssim.
 The former should be used for direct access to the TPM through the Linux kernel driver.
 The latter implements the protocol exposed by the Microsoft software TPM2 simulator.

NOTE: We deviate from this draft of the specification by increasing the value of TPM2_NUM_PCR_BANKS from 3 to 16 to ensure compatibility with TPM2 implementations that have enabled a lareger than typical number of PCR banks. This larger value for TPM2_NUM_PCR_BANKS is expected to be included in a future revision of the specification.
