dmesg from kernel 5.3, loading firmware

I'm trying to get somewhat accelerated video output out of my CuBox i4 (imx6 cpu, GC2000 graphics), but I don't have any luck with kernels 5.0, 5.2, or 5.3.

I tried recent Armbian and Fedora (30 and 31 beta).

The etnaviv messages from dmesg are:

[ 18.891291] etnaviv etnaviv: bound 130000.gpu (ops gpu_ops [etnaviv])
[ 18.895022] etnaviv etnaviv: bound 134000.gpu (ops gpu_ops [etnaviv])

I'll attach the complete dmesg - or you can see it here: http://ix.io/1WAW

Google brought me to Russell King's similar problem from June:
https://lists.freedesktop.org/archives/dri-devel/2019-June/224474.html

I don't know why the problem disappeared for him, though.

Initially I reported the problem at the armbian forum:
https://forum.armbian.com/topic/11539-no-hdmi-with-linux-image-dev-cubox-kernel-5211/

I'm more of a user than a developer, especially when it comes to the Linux kernel. But I can test switches or patches.

Any help would be appreciated!
