Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS interface with capabilities introduced for support of a TPM 2. TPM TIS for TPM 2 introduced the following extensions beyond the TPM TIS 1.3 (used for TPM 1.2): - A new 32bit interface Id register was introduced. - New flags for the status (STS) register were defined. - New flags for the capability flags were defined. Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2 on the backend side. Support the old TPM TIS 1.3 configuration if a TPM 1.2 is being used. A subsequent patch will then determine which TPM version is being used in the backend. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Michael S.
