Further looking at this spec, the log_area_minimum_length and
log_area_start_address only are described in
- Table 2 (TCG Hardware InterfaceDescription Table Format for TPM 1.2
Clients)
- Table 4 (TCG Hardware Interface Description Table Format for TPM 1.2
Servers)
but not in Table 7, ie. not for TPM 2.0.

Are they really needed for TPM2 or what do I miss?

Thanks

Eric
