/* the primary purpose of this function is to kick off things in
 * romstage that are time consuming. No more should be done at this
 * point than the bare minimum that will allow us to pick up the work
 * in the ramstage and not require lots of udelays.  ramstage will do
 * the rest. As it happens, that merely means 'turn off everything you can,
 * save the minimum long-delay bit that you need to get graphics going'. It's
 * important not to have the backlight on as people don't like display trash
 * on startup, even if I do.
