42config BOOTCOUNT_ENV
43 bool "Boot counter in environment"
44 help
45 If no softreset save registers are found on the hardware
46 "bootcount" is stored in the environment. To prevent a
47 saveenv on all reboots, the environment variable
48 "upgrade_available" is used. If "upgrade_available" is
49 0, "bootcount" is always 0, if "upgrade_available" is
50 1 "bootcount" is incremented in the environment.
51 So the Userspace Application must set the "upgrade_available"
52 and "bootcount" variable to 0, if a boot was successfully.
