REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3751 Current MM communicate routine from ArmPkg would conduct few checks prior to proceeding with SMC calls. However, the inspection step is different from PI specification. This patch updated MM communicate input argument inspection routine to assure that "if the `MessageLength` is zero, or too large for the MM implementation to manage, the MM implementation must update the `MessageLength` to reflect the size of the `Data` buffer that it can tolerate", as described by `EFI_MM_COMMUNICATION_PROTOCOL.Communicate()` section in PI specification.
