Hi Supreeth,
Some of the DXE references will have to be removed and copyright years need to
be updated. If that sounds reasonable then..

Subject: Re: [PATCH v1 11/18] StandaloneMmPkg: MM driver entry point library.

Some of the DXE references will have to be removed and copyright years need to be updated. If that sounds reasonable then..
[Supreeth] Ok.
