Change Details

``` 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? [[ https://lists.freebsd.org/pipermail/freebsd-hackers/2017-February/050584.html | 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 [[ https://man.openbsd.org/tpm.4 | 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. [[ https://lists.freebsd.org/pipermail/freebsd-hackers/2017-February/050584.html | This thread from hackers@ (2017-02) ]] suggests that version 2.0 is not implemented.

Also, TPM 2.0 devices are usually backward compatible and may work with our tpm(4) driver to some extent.
