/**
 * 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
 *
