    that they can be described at config time. * Added tilemap_memory object that is used internally for reading/     writing to memory that backs a tilemap. This object is used to     track a memory pointer that backs tilemap memory， and also is     designed to transparently handle all bus width and endianness     associated with reading and writing data in a tilemap. * Incorporated two tilemap_memory objects (basemem and extmem) into     the tilemap object and added accessors to them， as well as     read/write handlers for reading/writing to entries stored in the     memory. This means that tilemap get info callbacks can now easily     read data out of the tilemap in a generic way. * Rejiggered the initialization sequence for tilemap objects so that     the tilemap_manager is not required to be present at     instantiation.
