-- Bootcount:
- CONFIG_BOOTCOUNT_LIMIT
- Implements a mechanism for detecting a repeating reboot
- cycle, see:
- http://www.denx.de/wiki/view/DULG/UBootBootCountLimit
-
- CONFIG_BOOTCOUNT_ENV
- 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 Applikation must set the "upgrade_available"
- and "bootcount" variable to 0, if a boot was successfully.
