This menu is for boards that need a built-in DTB, as MIPS currently doesn't support appended DTBs it is the only way to load a DTB on boards stuck with a broken boot loader. But as no board has been added yet it only contain the entry for boards that don't need a built-in DTB, which do nothing as you pointed out.
A board is then added in this menu in patch 14, for some reasons git send-email didn't send the whole serie at once :(
