What I would like to know is why anyone is using appended DTBs in this day and age, when surely by now, Arm based boot loaders have realised that Arm moved to use device trees ages ago, and the kernel requires a DTB in addition to the kernel image itself. Appended DTB support was only there as a stop-gap for those boot loaders that were around before DTB support was added, and have no capability of dealing with a separate DTB. Come on. It's 2026. DTB has been supported on 32-bit ARM for fifteen years. Surely everyone's now got modern boot loaders. If not, it's time to say this: fix the boot loader. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
