+config BOOTCOUNT_ENV
+ bool "Boot counter in environment"
+ help
+ If no softreset save registers are found on the hardware
+ "bootcount" is stored in the environment. To prevent a
+ saveenv on all reboots, the environment variable
+ "upgrade_available" is used. If "upgrade_available" is
+ 0, "bootcount" is always 0, if "upgrade_available" is
+ 1 "bootcount" is incremented in the environment.
+ So the Userspace Application must set the "upgrade_available"
+ and "bootcount" variable to 0, if a boot was successfully.
