Move examples/ to examples/standalone
The current files in examples are all standalone application examples,
so put them in their own subdirectory for organizational purposes

Ensuring U-boot's MAC address can be set in hardware --------------------------------------------------------------------------- - -On the Internet - MAC addresses are very important. Short for Media -Access Control address, a hardware address that uniquely identifies -each node of a network. When things are not unique - bad things -can happen. This is why U-Boot makes it difficult to change MAC -addresses. - -To find out who has a MAC address, or to purchase MAC addresses, goto -the IEEE, at: -http://standards.ieee.org/regauth/oui/index.shtml - -To change your MAC address, there can not be a MAC address predefined in -U-Boot.
