Actually, I would hit the same problem (late visual feedback) with a
splash screen: we would need to wait for u-boot to be fully loaded,
which takes too much time.
(plus, the DE2 video driver only supports HDMI out for now, and I don't
have the skills to add MIPI-DSI support)
Having the status LED set up in the SPL allows almost-instant visual
feedback, which is what I'm looking for here.
