These are the changes for the TPM driver with a single major new feature: TPM bus encryption and integrity protection. The key pair on TPM side is generated from so called null random seed per power on of the machine [1]. This supports the TPM encryption of the hard drive by adding layer of protection against bus interposer attacks. Other than the pull request a few minor fixes and documentation for tpm_tis to clarify basics of TPM localities for future patch review discussions (will be extended and refined over times, just a seed).
