+ * Name: up_pminitialize
+ *
+ * Description:
+ *   This function is called by MCU-specific logic at power-on reset in
+ *   order to provide one-time initialization the power management subystem.
+ *   This function must be called *very* early in the intialization sequence
+ *   *before* any other device drivers are initialized (since they may
+ *   attempt to register with the power management subsystem).
+ *
+ * Input parameters:
+ *   None.
+ *
+ * Returned value:
+ *    None.
