Small patch to fix boot problem when power is cut in U-Boot

During the start of U-Boot, for a short time, the reset controller is reprogrammed. In the old version, when power cuts at this moment, the system is unable to boot from DataFlash. The new version fixes this by using temporary settings, that don't prevent the system to boot.

Patch and Images are included.
