| 26 | help | |
| 27 | A bootcount driver for the RTC IP block found on many TI platforms. | |
| 28 | This requires the RTC clocks, etc, to be enabled prior to use and | |
| 29 | not all boards with this IP block on it will have the RTC in use. | |

31 | config BOOTCOUNT_ENV |
| 32 | bool "Boot counter in environment" | |
| 33 | help | |
| 34 | If no softreset save registers are found on the hardware | |
| 35 | "bootcount" is stored in the environment. To prevent a | |
| 36 | saveenv on all reboots, the environment variable | |
| 37 | "upgrade_available" is used. If "upgrade_available" is | |
| 38 | 0, "bootcount" is always 0, if "upgrade_available" is | |
| 39 | 1 "bootcount" is incremented in the environment. | |
| 40 | So the Userspace Application must set the "upgrade_available" | |
| 41 | and "bootcount" variable to 0, if a boot was successfully. | |
