| 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. |
