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/...
As well as these dts patches:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=57... https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=d5... https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=e5... https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=8e...
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=67...
I inserted this one here so the following stuff would cherry-pick ok, I think that was the right thing to do.

Those combined with a new enough u-boot should get you video output on most devices supported in upstream u-boot.
Indeed, this gets me graphics on my Cubietruck at least.
Thanks!
This looks great, thanks. The video output support in Debian is going to be very much appreciated. It looks like I don't really need to do anything other than just installing the U-Boot bootloader by

And can simply delegate everything else to the Debian installer :-)
Just one suggestion. It would be really nice if the Debian installer could present itself on all the available consoles, so that the user can use any of them for providing input to the installer.
Otherwise there will be a need to provide separate SD card images for the HDMI console (for the Raspberry Pi wannable competitors), the UART serial console (A10/A20 development boards without HDMI) and the USB OTG serial gadget console (for the tablets without HDMI). Instead of just having only a single SD card image to handle everything automatically.
Oh, and one more suggestion. The SD card partitioning could be also improved in order to make it more user friendly. Right now the user may be confused by the Debian installer regarding what to do with the existing partition on the SD card (yes, it can be safely erased since the installer is running from RAM and does not rely on the data from that partition anymore).
