[PATCH] tpm: add bios measurement log
According to the TCG specifications measurements or hashes of the BIOS code and data are extended into TPM PCRS and a log is kept in an ACPI table of these extensions for later validation if desired. This patch exports the values in the ACPI table through a security-fs seq_file.
