BBM is part of USER_DATA section, so we should remove it twice

Maybe you mean "is already part" and as such the end of the sentence
should be that "we should *not* remove it twice"?
yes indeed.

Thanks !


This was working ok because we are on the safe size, advertising that
there was 2 bytes less available than in reality.

But we can't change old platforms, since it may lead to a different ECC
strength, so, introduce a legacy flag for old platforms, and switch the
new platforms to the correct count.
