Goal and why this matters

TEE measurements are critical to enforce fool proof confidentiality through the hardware root-of-trust mechanism. This requires remote attestation of the TEE (TDX and SNP) measurements by comparing the hash values with reference values available with Trustee. Currently, our build pipeline doesn't compute and publish the reference hash value for initrd to Trustee/RVPS. 

The goal of this story is to complete the internal documentation on the implementation of reference value generation of measurements for the initrd with TDX/SNP TEE at build pipeline for Trustee RVPS and do end-to-end testing as per the internal documentation.

Refer https://issues.redhat.com/browse/KATA-3977 for guidance on documentation.

Acceptance Criteria

Successful documentation (input to the user guide creation for customer documentation) and end-to-end testing of the initrd reference value in Trustee for remote attestation based on the internal documentation.
