New u-boot command for status of USER button on BeagleBoard-xM
Modified bootcmd to check the staus at boot time and set
filename of the boot script.
* Moved to a BeagleBoard specific file.
* Removed changes to default boot command from adding userbutton
command.
* Made to handle pre-xM boards.
* Flipped polarity of the return value to avoid confusion. Success (0)
is when the button is pressed. Failure (1) is when the button is NOT
pressed.
* Used latest revision getting function.
* Used latest macros for board revision.
* Added xM-C revision definition (optional, since it was default)
* updated default configuration with UserButton functionality
* Added a separate bootenv variable to load a user defined .txt file
* Added an example, showing how a different environment file can be loaded with
the user button pressed
