On WHL platform, we need to pass through TPM to Secure pre-launched VM. In order to do this, we need to add TPM2 ACPI Table and add TPM DSDT ACPI table to include the _CRS. Now we only support the TPM 2.0 device (TPM 1.2 device is not support). Besides, the TPM must use Start Method 7 (Uses the Command Response Buffer Interface) to notify the TPM 2.0 device that a command is available for processing.
