TCG TIS 1.3 compliant TPM driver to use the TPM as hardware crypto library.
The TPM 2.0 architecture, commands and structures are defined in the set of 4 Trusted Platform Module Library Specification, Family "2.0" specifications that that can be found at http://www.trustedcomputinggroup.org/resources/tpm_library_specification
The "PC Client Specific TPM Interface Specification (TIS), Version 1.3" that was used for this implementation can be found at http://www.trustedcomputinggroup.org/resources/pc_client_work_group_pc_client_specific_tpm_interface_specification_tis
All the information to get going is in SPITIS_TPM20.h!
