This is also why I'm mostly focussing upstream, which has resulted in
Fedora 21 and the upcoming Debian release supporting allwinner devices
ootb (albeit only headless) and the upcoming F-22 release will have
much improved allwinner device support, supporting more devices, and
supporting video output, etc.
Speaking of which, if someone were to identify a suitable set of
simple-fb backports for 3.16 and they are reasonably self contained I'd
happily backport them to the kenrel which is going to be in the next
Debian release too...
You will need all patches by me and by "Luc Verhaegen" from here:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/video/fbdev/simplefb.c
As well as these dts patches:

Those combined with a new enough u-boot should get you video output on most
devices
supported in upstream u-boot.
Ian, can you live with overloading the high machine-id bits to
deliberately break old kernels when not compiled with old kernel
compatibility?
It kind of sucks, but so do all the options it seems, I guess we can
live with it...
Ok, I'll go and merge the v2 patch then. Siarhei, I'm working on a
linux-sunxi-3.4 fix for the sun5i PLL6 issue, please do not add a
patch to the linux-sunxi-3.4 kernels claiming "COMPAT_REV 1" compatibility
until that patch is done and merged.
Thanks & Regards,
Hans
