+ * non-secure world system. In general, the established channel allows the
+ * secure world applications initiate requests or notifications to the non-secure
+ * world.
+ *
+ * For particular devices, the secure world can only perform operations on the
+ * display when in the TUI session if device-specific setup is done by the
+ * non-secure world. Besides, the non-secure world could allocate framebuffer
+ * for the secure world application if the memory is limited in the secure world
+ * on specific devices.
+ *
+ * Currently, supported requests are to start / stop the secure display mode and
+ * to allocate framebuffer.
+ *
+ * This header file needs to be synced on both the Trusty and the Android
