Memory types for mapping

Types of memory for mapping

The UDD core implements a default ->mmap() handler which first attempts to hand over the request to the corresponding handler defined by the mini-driver. If not present, the UDD core establishes the mapping automatically, depending on the memory type defined for the region.
