    14 * Description:

    15 * Implements common print functions used in debug mode for all security components.

    16 * A component that wants to use these common debugging functions should define its

    17 * own log header file and include this header file. In the component's header file,

    18 * the followings should be defined:

    19 * _LIT8(KComponentName, "[TheComponentName]");
