Try to be less smart (focused on the one target/one use-case), instead reduce the rpi-firmware package to a selectable list of (verbatim) installed firmware files. - change rpi-firmware config handling from rpi-variant/rpi-flavour choices to bootcode.bin, pi-default/-extended/-cut-down and pi4-/default/-extended/-cut-down selection - add BR2_PACKAGE_RPI_FIRMWARE_CONFIG_FILE option to select installable config.txt file - remove config.txt modify code/handling from raspberry post-image.sh script - add different customized config.txt files to the raspberry board section - change dtoverlay krnbt from 'dtoverlay=miniuart-bt,krnbt=on' to extra line with explanation comment - change raspberry defconfigs to select appropiate rpi-firmware and config.txt files - change genimage-raspberrypi4.cfg/genimage-raspberrypi4-64.cfg to use start4.elf and fixup4.dat - update board/raspberrypi/readme.txt (add optional files fixup4.dat, start4.elf and zImage) With this changes a better support for custom use-cases should be possible, specially multi-target SD cards as suggested by Stefan Agner ([1]).
