tpm(4): Add the STANDARDS and HISTORY sections. Also, link to the homepage of the BSSSD project, which developed the original driver.
Questions:
- Are we sure that tpm(4) is implementing TPM specification version 1.2? This thread from hackers@ (2017-02) suggests that not really. OpenBSD uses a very similar driver and it claims that its tpm(4) driver implements version 1.2 of the specification (see OpenBSD's tpm(4) manual page).
- Are we sure that tpm(4) is not implementing TPM specification version 2.0? If so then maybe we could mention it in the manual page. This thread from hackers@ (2017-02) suggests that version 2.0 is not implemented.
@kevans told me that probably tpm(4) only support 1.2. Also, TPM 2.0 devices are usually backward compatible and may work with our tpm(4) driver to some extent.
