From production view this is standard test executed during production on
all linux based foxmc cards. On CENT2 HW defined memory region is zero means that some DDR accesses are done by memory_post_dataline and memory_post_addrline but pattern tests are skipped that's why mem_regions is fast there.
On ls102x for the complete DDR region of 1GiB memory_regions_post_test takes approx. 4min and this is too much for production, so this patch defines only 1MiB region as compromise.
