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) shall: 1. Consume the gSmmBaseHobGuid HOB for the relocated smbases for each Processor. 2. Execute the early SMM Init. This patch just provides the SmmRelocationLib class.
