Then I'm confused, because video_hw_init() is what configures and enables the
video display. So if that function succeeds (i.e. returns non-NULL), then
U-Boot will put the console onto the video display. You said you wanted me to
implement some mechanism where I enable the display, based on the value of the
video-mode variable, without putting console on the display. However, from you
just said, it appears that this mechanism already exists.
