+/**
+ * enum fastrpc_map_flags - control flags for mapping memory on DSP user process
+ * @FASTRPC_MAP_STATIC: Map memory pages with RW- permission and CACHE WRITEBACK.
+ * The driver is responsible for cache maintenance when passed
+ * the buffer to FastRPC calls. Same virtual address will be
+ * assigned for subsequent FastRPC calls.
+ * @FASTRPC_MAP_RESERVED: Reserved
+ * @FASTRPC_MAP_FD: Map memory pages with RW- permission and CACHE WRITEBACK.
+ * Mapping tagged with a file descriptor. User is responsible for
+ * CPU and DSP cache maintenance for the buffer. Get virtual address
+ * of buffer on DSP using HAP_mmap_get() and HAP_mmap_put() APIs.
+ * @FASTRPC_MAP_FD_DELAYED: Mapping delayed until user call HAP_mmap() and HAP_munmap()
+ * functions on DSP. It is useful to map a buffer with cache modes
+ * other than default modes. User is responsible for CPU and DSP
+ * cache maintenance for the buffer.
+ * @FASTRPC_MAP_FD_NOMAP: This flag is used to skip CPU mapping,
+ * otherwise behaves similar to FASTRPC_MAP_FD_DELAYED flag.
+ * @FASTRPC_MAP_MAX: max count for flags
