The UEFI BIOS already hashes the contents of the loaded image, so the initrd and the command line of the binary are recorded. Because manually added LoadOptions are not taken into account, these should be recorded also. This patch logs and extends a TPM PCR register with the LoadOptions. This feature can be enabled with configure --enable-tpm The PCR register index can be specified with configure --with-tpm-pcrindex=<NUM>

coding-style-wise looks ok to me now. @kaysievers? @msekletar? |

Looks fine to me. As long as it is off by default, and only for the "distro" to decide to enable it for which of the registers. |
