On second thought, I think it might be a better approach to add additional config options to /etc/default/raspi-firmware, so that the config.txt file it generates works with u-boot. Adding a configuration directory at /etc/default/raspi-firmware.d would also be nice so that upstream distributions can set these settings without conflicting with Debian. > * An option for U-Boot that will check if the bootloader image in the > firmware partition is up-to-date and copy it if it is out of date. This might not be necessary. flash-kernel already has code that does this, and there are PRs that will add support for Raspberry Pi 4B (and other) machines which will make things work here.
