In case a TPM2 is attached, search for a TPM2 ACPI table when trying
to get the event log from ACPI. If one is found, use it to get the
start and length of the log area. This allows non-UEFI systems, such
as SeaBIOS, to pass an event log when using a TPM2.

Do you think that QEMU with TPM 1.2 emulator turned on would be a viable
way to test this?

I'm anyway more worried about breaking existing TPM 1.2 functionality
and that requires only QEMU without extras.

The 1.2 bits should be functionally the same as before, right?
