    unicore32: simplify detection of memory zone boundaries · 1b02ec01
    Mike Rapoport authored
    free_area_init() only requires the definition of maximal PFN for each of
    the supported zone rater than calculation of actual zone sizes and the
    sizes of the holes between the zones.
    
    After removal of CONFIG_HAVE_MEMBLOCK_NODE_MAP the free_area_init() is
    available to all architectures.
    
    Using this function instead of free_area_init_node() simplifies the zone
    detection.
