Check and execute the pending TPM request and Lock TPM.

|
The TPM request may come from OS or BIOS. This API will display request information and wait
|
|
for user confirmation if TPM request exists. The TPM request will be sent to TPM device after
|
|
the TPM request is confirmed, and one or more reset may be required to make TPM request to
|
|
take effect. At last, it will lock TPM to prevent TPM state change by malware.
|
|
|
|
This API should be invoked after console in and console out are all ready as they are required
|
|
to display request information and get user input to confirm the request. This API should also
|
|
be invoked as early as possible as TPM is locked in this function.
