The UEFI v2.10 spec defines the protocol EFI_CC_MEASUREMENT_PROTOCOL
to enable (for example) RTMR-based boot measurement for TDX VMs.

implementation, TPM measurement in TDVF is disabled when
RTMR measurement is enabled.

some comments.
Forward the email into the EDK2 dev and linux-coco.

The direct boot patch needs to be patched as well. Here is the link.
