Anyway, when you will have implemented read-only and volatile flags for env vars, this patch will no longer be needed. But with the current code, there is no way board-specific code can create a board revision env var and make it read-only, except with this patch.
Correct, so far we don't support custom read-only variables. But if we add these, then in a generic way, and definitely not for a single, specific variable. This is a lesson we learned form experience.
I didn't follow this thread, but would it be an option to create a command for these kind of things, instead of read-only variables? e.g. some like
if get revision out; then; echo $out; else; echo revision not supported fi;
Just a though, regards,
