the mem_map structure containing the size of SDRAM is used in various cache functions in cache_v8.c thus we need to update it with the sdram size the board is configured with as well. Without this the cache functions do not get setup properly and can hang in the case where a board reports more SDRAM than defined in PHYS_SDRAM_SIZE.
