37 | help | |
38 | A bootcount driver for the RTC IP block found on many TI platforms. | |

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. | |
