I am wondering what the intention is for the linux-raspberrypi package versus the linux-raspberrypi4 for the armv7 RPis. I have noted that the linux-raspberrypi4 package installs and boots on PiB2v1, PiB3, PiB3+ and PiB4. The linux-raspberrypi package will not boot a Pi4B. Is there a reason to not use the linux-raspberrypi4 kernel on lesser Pis? I ask this as I am working on an audio device which is for all Pis and have decided to use the RPi4 kernel for all of them I have not noticed any problems or issues related to its use on the Pi2 or Pi3. If there is not a reason to not use it on lesser Pis, why not get rid of the other version?
