Re: [PATCH 8/8] MdeModulePkg: Deprecate Smm* PPIs.

["Gao, Liming" <liming.gao@intel.com>]

To keep compatibility, I suggest to update MdeModulePkg PPI definition to include MdePkg one, then typedef structure name and define macro name for SMM one. MdePkg SMM protocol uses this way to refer to MM protocol. 

Thanks
Liming
