Here my video where I show how to download and install everything. And some gameplay.
Again thank you to @balbes150 for the images.
 

It has gotten a lot easier to use Panfrost now.
Download one of @balbes150 5.x Bionic images for your device. 
The panfrost module is already added, all that needs to be done is installing the mesa drivers. For that I made a script. 
Download the file here in attachment and unpack it. 
Go into the folder Panfrost
 
cd Panfrost sudo ./installPanfrost.sh Install all for best results.

Panfrost has improved a lot on 5.4. Many games now work normally, some still have some smaller problems. It has become usable.
Greetings, NicoD

Edit : Script update. You now can upgrade the mesa and drm drivers after installation
Update 2 : Also Lima support now. 
 
 
 
 
 
installPanfrost.sh

@ning
It worked. Thanks.

So in the procedure for LePotato is enough to change:
"$FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0"
in:
"python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0"
and so the produced "u-boot.bin.sd.bin" boots.

Legenda of test result:
(yes) means that HDMI to HDMI and HDMI to DVI both work
(HDMI only) means HDMI to HDMI works
no () means that HDMI to HDMI and HDMI to DVI both don't work.
 
PS
To change resolution from UART console I used for example:
$ xrandr -d :0 --output HDMI-1 --mode 1920x1080

Other test performed. I am starting to understand better the "HDMI to DVI" working/not working laziness problem:
 
HDMI to DVI works BUT, just after the boot, I have to move the mouse to wake up the monitor and get the desktop (I usually interact with the SBC via the uart console).
 
That's with the last:
