44 bool "Boot counter in environment"
45 help
46 If no softreset save registers are found on the hardware
47 "bootcount" is stored in the environment. To prevent a
48 saveenv on all reboots, the environment variable
49 "upgrade_available" is used. If "upgrade_available" is
50 0, "bootcount" is always 0, if "upgrade_available" is
51 1 "bootcount" is incremented in the environment.
52 So the Userspace Application must set the "upgrade_available"
53 and "bootcount" variable to 0, if a boot was successfully.
