Do the attestation report examination and enable MMIO.


It seems in both guest side (this patch) and host side
(PATCH 7 tsm_report_show()), if the SW wants to reach the latest TDI
report, they have to call get TDI status verb first.

As this is about UABI, if this is expected, it would nice that we can
explicitly document this requirement.

We do need to document the UABI.

Or we just get the fresh report from the device all the time?

I'd do just that (and it should not really change as long as the TDI stays is in LOCKED/RUN) but since you are asking - I suspect there is a caveat, is not there? Thanks,
