- 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 Application must set the "upgrade_available"
- and "bootcount" variable to 0, if a boot was successfully.
