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. This patch set add spl_early_init. it can be called in board_init_f. So we can fix this issue by using spl_early_init.
