+ProvenCore Dispatcher
+=====================
+
+ProvenCore dispatcher (PnC-D) adds support for ProvenRun's ProvenCore micro-kernel
+to work with Trusted Firmware-A (TF-A).
+
+ProvenCore is a secure OS developed by ProvenRun S.A.S. using deductive formal methods.
+
+Once a BL32 is ready, PnC-D can be included in the image by adding "SPD=pncd"
+to the build command.
