  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.

  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.
