[PATCH V5 00/13] Enable Tdx measurement in OvmfPkgX64

Min Xu

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4243

Tdx measurement (RTMR based measurement) is enabled in OvmfPkg/IntelTdx.
This patch-set enables the feature in OvmfPkgX64 as well.

Patch #1:
  Introduce TDX_MEASUREMETNS_DATA in SEC_TDX_WORK_AREA. That is because
  the RTMR measurement of TdHob and Configuration FV (CFV) are executed
  in very early stage of boot process. At that time the memory service is
  not ready and the measurement values have to be stored in OvmfWorkArea.

Patch #2:
  Introduce TdxHelperLibNull which is the NULL instance of TdxHelperLib.

Patch #3:
  Introduce SecTdxHelperLib which is the instance of TdxHelperLib for SEC
  Phase. This patch adds the stubs of TdxHelperLib functions. The actual
  implementation are in the following patches.

Patch #4:
  Re-use the data struct of PLATFORM_FIRMWARE_BLOB2_STRUCT for
  FV_HANDOFF_TABLE_POINTERS2.
  
Patch #5-7:
  These 3 patches move the functions ( which were implemented in
  PeilessStartupLib and PlatformInitLib ) to TdxHelperLib. So that they
  can be called in both OvmfPkgX64 and IntelTdxX64.

Patch #8/9:
  These 2 patches are the changes for tdx measurement in IntelTdxX64.

Patch #10-13:
  These 4 patches are the changes for OvmfPkgX64 to enable Tdx
  measurement.

Code: https://github.com/mxu9/edk2/tree/TdxMeasurementInOvmfX64.v5

v5 changes:
 - Re-organize the patches. Its purpose is not only to simplify review, but also
   to simplify testing. https://edk2.groups.io/g/devel/message/99209

v4 changes:
 - To make the code reviewable, the implementation of
   TdxHelperBuildGuidHobForTdxMeasurement is split into 4 patches (5-8).
 - Call Sha384HashAll instead of the 3 Sha384XXX functions so that we
   need to allocate memory in SEC phase.

v3 changes:
 - Use the definition of PLATFORM_FIRMWARE_BLOB2_STRUCT in
   Library/TcgEventLogRecordLib.h.
 - Rename TDX_ENABLE as TDX_MEASUREMENT_ENABLE because this flag is
   introduced for Tdx-measurement.
 - Split the patch of SecTdxHelperLib into 2 separate patches (#3/#9).
   Patch#3 implements TdxHelperMeasureTdHob and TdxHelperMeasureCfvImage.
   Patch#9 implements TdxHelperProcessTdHob. This is to make the patches
   more reviewable. The duplicated codes of TdxHelperProcessTdHob are
   deleted in Patch#9 as well.
 - The implementation of TdxHelperBuildGuidHobForTdxMeasurement and update
   of PeilessStartupLib are in one patch (#5). Because the implmentation
   of TdxHelperBuildGuidHobForTdxMeasurement was once in PeilessStartupLib.

v2 changes:
 - Split the patch of TdxHelperLib into 4 separate patches. So that it is
   more reviewable.
 - Add commit message in Patch#1 to emphasize that the tdx-measurement in
   OvmfPkgX64 is supported in SEC phase.
