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]).
