+Subject: [PATCH 07/27] arm_ffa: introducing armffa command
+
+A new armffa command is provided as an example of how to use
+the FF-A helper functions to communicate with secure world.
+
+The armffa command allows to query secure partitions data from
+the secure world and exchanging messages with the partitions.
