New BCM4908 family based routers will use U-Boot bootloader. That will require using a totally different firmware format. Kernel has to be put in a FIT image. OpenWrt has some helpers for generating .its files but they don't fit BCM4908 requirements and there is no simple way of extending any of them. The best solution seems to be storing an .its template. BCM4908 bootfs may: 1. contain extra binaries (other than kernel & DTB) 2. include multiple DTB files 3. store device specific U-Boot configurations with custom properties Such setups are too complex to generate using shell script. Raw .its file on the other hand seems quire clean & reasonable. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
