Dear Albert ARIBAUD,

I can not recommend a proper place for all boards cause this parameter is highly is board specific.
Understood -- each board maintainer must select an adapted location for the mirror.
I'm not conviced that ech board maintainer should do that, and I somewhat doubt the approach taken.
The main purpose of the patch (as I see it) is to find out which functions might be candidates to write to bss too early. There is not that much board specific code involved there.
If we can generate a slist of functions that are called before relocation, we can use nm to check if these refernce any sumbols in bss. We could even generate black / white lists.
Just to clarify:
I see Andreas' proposal as a debug tool, notintended to ever be applied to a branch, but to be kept and applied to local developer repositories during debug.
It seems you, Wolfgang, are considering this more like a tool that would end up in the u-boot source tree and be e.g. run systematically after a build, even if the builder had no intent of debugging. Am I right?
If so, then yes, a tool that would analyze the ELF binary would be a good approach.
Best regards,
Wolfgang Denk
Amicalement,
