Hello,
We have devices that are all based on cm4 based hardware, but which can have extra plug in modules that need to be activated with a dtoverlay line in /boot/firmware/config.txt. However, due to using secure boot we can't easily change config.txt to enable those modules. I was thinking of using the include directive to include a second file outside of boot.img with only those dtparam lines, but then i read in the manual that devices with EEPROM bootloaders do not support the include directive. And i'm not even sure that such a file would be accessible by the bootloader if it is not included in the boot.img file.
Is there any way to do this without making different images for each combination of modules?
