Add comment describing the interaction between dcache and memory region attributes. (dcache_xfer_memory): Add comment describing benefits of moving cache writeback to a higher level. (dcache_struct): Removed cache_has_stuff field. This was used to record whether the cache had been accessed in order to invalidate it when it was disabled. However, this is not needed because the cache is write through and the code that enables, disables, and deletes memory regions invalidate the cache. Add comment which suggests that we could be more selective and only invalidate those cache lines containing data from those memory regions. (dcache_invalidate): Updated. (dcache_xfer_memory): Updated. (dcache_alloc): Don't abort() if dcache_enabled_p is clear. (dcache_xfer_memory): Removed code that called do_xfer_memory() to perform a uncached transfer if dcache_enabled_p was clear. This function is now only called if caching is enabled for the memory region. (dcache_info): Always print cache info. * target.c (do_xfer_memory): Add attrib argument. (target_xfer_memory, target_xfer_memory_partial): Break transfer into chunks defined by memory regions, pass region attributes to do_xfer_memory(). * dcache.c (dcache_read_line, dcache_write_line): Likewise. * Makefile.in (SFILES): Add memattr.c. (COMMON_OBS): Add memattr.o. (dcache.o): Add target.h to dependencies. * memattr.c: New file. * memattr.h: Likewise.
