+Environment variables
+---------------------

+A board may chose to look at the environment for decisions about falcon
+mode. In this case the following variables may be supported:
+
+boot_os : Set to yes/Yes/true/True/1 to enable booting to OS,
+ any other value to fall back to U-Boot (including
+ unset)
+falcon_args_file : Filename to load as the 'args' portion of falcon mode
+ rather than the hard-coded value.
+falcon_image_file : Filename to load as the OS image portion of falcon
+ mode rather than the hard-coded value.
