+    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.

+Subject: [PATCH] BeagleBoard: Adjust boot command on USER button
+
+When the USER button is pressed, the default boot command will attempt
+to load user.scr.  If that fails, it will try to load a ramdisk image.
+
+This version also sets the rootfstype and assumes that the userbutton
+command returns success (0) when the button is pressed.  It also really
+attempts to load the user.scr file.
