Well, slightly less efficient for the (uncommon) situation where src/dest overlaps in return for significantly more efficiency for the situation where they don't.

That's another option, but more work for implementers - So I would prefer this trivial patch instead. But I'll drop it if you disagree. -- Bye, Peter Korsgaard _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
