I agree with Jiewen that these should not be a part of this series. Can you push
these in a separate series?

Subject: Re: [PATCH v1 17/18] StandaloneMmPkg: Add application to test MM communication protocol.
Hi Supreeth,
I agree with Jiewen that these should not be a part of this series. Can you push these in a separate series?
[Supreeth] Jiewen's comment was "they are only for unit test. I do not think we should check in them". I will not send these patches as of now, if you do need them, Let me know.
cheers,
Achin
