The "auto" policy is used for the "AUTOREV" recipe, the current BB_SRCREV_POLICY are: "clear" (default) and "cache": * When "clear", the "AUTOREV" recipe would not be cached * When "cache", the "AUTOREV" would be cached, but it didn't get the lastest revision. The "auto" policy is much like the "cache" except that it will try to get the latest revision.
Drop it since it may break things.
