Changes

== Mantenience Maintenance ==

With the old schema 3 different software existed (x-loader, u-boot, kernel) that did exactly the same job, so you had to reconfigure the board, increasing the complexity of mantenience maintenance for the board system and provide a major bug source because we had to assure that all software was aligned with all changes. Also, from a second point of view, we did the job three times so the boot process was more complex and slow.
