Event log

[krystian-hebel]

This adds support for the DRTM TPM event log, both for TPM1.2 (aka SHA1 Event Log Entry Format [1]) and TPM2.0 (aka Crypto Agile Log Entry Format [2]).

It is up to the bootloader to provide address and size of the event log. DRTM specification [3] defines a new ACPI table containing this information, as well as other pointers and data related to DRTM. Bootloader may prepare and pass another block of memory if this table is not present.

If a bootloader does not fill up the event log address or size, LZ will not log any entries, but it will continue to extend PCRs nonetheless.
