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.

Best regards,

Wolfgang Denk
