I see this error here with the test cases:

The diff is in the address of the TPM log ... Not good. I don't know how 
we could have it ignore the address or not build the TPM2 table with an 
address for a log. It would be good to have test cases.

The log that the TPM2 ACPI table points to is needed for a BIOS, UEFI 
does not need it (but we don't typically know whether BIOS or UEFI will 
run). So we could introduce a property no-acpi-log and have the test 
cases set this to 'on' and get a NULL pointer for the 'Log Address'. You 
could use the following in a patch:
