The BR2_DEPRECATED logic is a lot less useful than the legacy handling, because the symbols just disappears without warning to the user. For example, we had a few defconfigs that were using deprecated symbols (which were not actually used because BR2_DEPRECATED wasn't set) so these didn't build the expected code anymore. Also, the idea behind BR2_DEPRECATED is that you can easily revive it again if there is interest. However, it is relatively easy to revert the removal of a package as well. The deprecation is also more effort because it has to be removed twice: once when deprecating, and once when really removing. It doesn't make sense to add a legacy entry for BR2_DEPRECATED. Users who actually used it will get legacy warnings instead. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
