you must run two commands one to compile u-boot with the codec node, the other is to compile and copy the new codec with r40/v40 support. and finally it remains to load the modules, there are two ways one is to load it manually: sudo modprobe sun8i-codec-analog sudo modprobe sun4i-codec and the second way is to add the two previous commands in /etc/rc.local which loads the modules automatically. first try the manual commands, if after loading manually the sound card appears you should modify rc.local so that it loads automatically

yes, you can test in m2-berry, and it should work at least from kernel 5.4.x

A volunteer. What can I test and confirm if it works correctly?

what happens is this is just the module, for them to work you need to add the codec node to sun8i-r40.dts and sun8i-r40-bananapi-m2-ultra.dts, just give me a few hours to fix some details and give you details how to compile u-boot with changes
