Why do you think you have to provide this additional information? Let the frame buffer driver compute them. Therefor, as William mentioned, specify the cmdline variable in file /boot/uEnv.txt like > cmdline=coherent_pool=1M quiet *video=HDMI-A-1:800x480M@60e* > cape_universal=disable init=/lib/systemd/systemd > Note the "M" after the resolution here. It requires individual calculation of the timings (in contrast to reading them from a pre-defined table, see framebuffer documentation for details). That way you can skip EDID and specify any resolution in a convenient way. I guess RPi provides a similar feature, and you need not manually handle them using the config.txt file.
