From 5b39832e184f3d00b0b35f006706d4c7e9a54fae Mon Sep 17 00:00:00 2001 From: Kun Qin Date: Wed, 26 Jan 2022 03:39:05 +0800 Subject: 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.
