Jiaxin, can you kindly share a PR in GitHub so that it will be easier to review?

Thanks,
Ray

Subject: [PATCH v1 00/13] Add SmmRelocationLib

Intel plans to separate the smbase relocation logic from
PiSmmCpuDxeSmm driver, and the related behavior will be
moved to the new interface defined by the SmmRelocationLib
class.

The SmmRelocationLib class provides the SmmRelocationInit()
interface for platform to do the smbase relocation, which
shall provide below 2 functionalities:
1. Relocate smbases for each processor.
2. Create the gSmmBaseHobGuid HOB.

With SmmRelocationLib, PiSmmCpuDxeSmm driver (which runs at
a later phase) can be simplfied as below for SMM init:
1. Consume the gSmmBaseHobGuid HOB for the relocated smbases
for each Processor.
2. Execute the early SMM Init.
