Andrew F. Davis's below patch broke rk3288 based board. that is because we call spl_init in board_init_f which is at very early stage. What Andrew want to fix is calling spl_init very late. That patch will make malloc_base, limit, ptr not initualized in spl_init when we call spl_init in board_init_f. It seems impossible to meet two requirement in spl_init. So i simply init malloc_base, limit, ptr before spl_init.
