+               "bootcount" is stored in the environment. To prevent a
+               saveenv on all reboots, the environment variable
+               "upgrade_available" is used. If "upgrade_available" is

+               1 "bootcount" is incremented in the environment.

+               and "bootcount" variable to 0, if a boot was successfully.
