Dear Rob Herring,

Maybe can be mkenvimage a solution (tools/mkenvimage) ? It creates an environment image from a simple ASCII text. The resulting image could be concatenated together with u-boot and in CONFIG_EXTRA_ENV_SETTINGS we could have for all boards a way to load it. Only a first idea, but as we recognize the issue, any idea to solve it ?
I definitely agree that we should move this out of C code and support standalone text files as input. IIRC, CONFIG_EXTRA_ENV_SETTINGS is replaced by any separate environment. I think it also needs to support being merged with a separate environment.
Why would you ever want to compile this into U-Boot at all? Then any changes you need to make mean compiling and installing a new U-Boot, which is something you normally don't want to do.
U-Boot is perfectly able to import such settings from text files (or text blobs stored somewhere, even attached to the U-Boot image, if you want), so just use the text files separately, instead of hard compiling them into the code.
Best regards,
