So I wonder if sysupgrade is working at all?
This is partially handled by the following patches now: 950-0247-ARM-dts-Add-model-specific-compatible-strings.patch 950-0253-BCM270X_DT-Add-Pi-3-dts-files.patch I'll adapt your patch for the ones that are still missing, and use upstream names for compute modules.
