主题: [edk2-devel] [PATCH v2 2/6] MdePkg: MmCommunication2: Update
MM communicate2 function description

Current MM communicate2 function definition described input arguments
`CommBufferPhysical`, `CommBufferVirtual` and `CommSize` as input only,
which mismatches with the "input and output type" as in PI specification.

This change updated function descriptions of MM communite2 definition to
match input argument types.
