Not everyone is using binary blobs from Rockchip. On my rock5b (rk3588), I'm building the bootloader using buildroot, which is using upstream TrustedFirmware-A (v2.12). > In short, I don't know where to go with that additional piece of > information, but this is a bit bigger than simply moving things around and > adding compile-time tests for overlay application. This is significant information indeed. Kind regards, Niklas
