The MISC_MM_COMMUNICATE_BUFFER stored the FF-A direct message registers in a DIRECT_MSG_ARGS structure. Populating and reading it required manually re-indexing every register (EventSvcArgs->Arg4..Arg17 into DirectMsgArgs.Arg0..Arg13). This shifted the register positions and left the buffer layout inconsistent with the raw FF-A argument register file, making it error prone to correlate a slot with its architectural register.
