I agree that that could be the case. Would be interesting to figure out
what exactly is needed to get the upstream kernel to work properly
with allwinner's u-boot.

p.s.

Did I understand correctly that you are working on a kms (or fbdev) driver
for the H3? A fellow Dutch hacker (Jelle van der Waa, added to the Cc) is
looking into adding H3 video console support to upstream u-boot. If you
already have a lit-up display with an upstream kernel it would be great
if you could share that, even if it is still wip.
