What for? It is not important.

This will be improve with patch. It's overkill. We can of course make patch submission to U-Boot an overregulated bureaucratic procedure. The EU gives plenty exaples of such regulations which keep lots of people busy producing nothing but hot air. We're engineers howver. Let's be thourough, but efficient.
