I looked at that but that seemed quiet complicated to implement, not to mention that it needed quiet a lot of arch specific code. On the other hand having the DTB built in like this was trivial and would be portable to every architecture, so that seemed like the best way to me. > What architecture and bootloader are you using that necessitate this? MIPS with an antic u-boot version patched by the board vendor to use some non standard image format. Updating the boot loader is currently not an option because of the lack of documentation for the board/SoC.
