+ Enable save environment support in SPL after setenv. By default
+ the saveenv option is not provided in SPL, but some boards need
+ this support in 'Falcon' boot, where SPL need to boot from
+ different images based on environment variable set by OS. For
+ example OS may set "reboot_image" environment variable to
+ "recovery" inorder to boot recovery image by SPL. The SPL read
+ "reboot_image" and act accordingly and change the reboot_image
+ to default mode using setenv and save the environemnt.
