  28           A bootcount driver for the RTC IP block found on many TI platforms.
  29           This requires the RTC clocks, etc, to be enabled prior to use and

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