/*
 * NOTE:  The flash drivers are called by the file system code and the
 *  flash programming tools.  It is never appropriate to call ERR_FATAL
 *  macro directly.
 *  In the flash programming tools, ERR_FATAL is not defined at all.  In
 *  AMSS, even though ERR_FATAL is defined, it makes calls that try to log
 *  to the file system and if we just got a fatal error by being called
 *  by the file system code, then we don't want to try to use the file
 *  system to log the error.  So the wrapper macro turns off logging and
 *  then displays the error message in the normal fashion.
 *  The version of this fatal error macro for flash tools merely goes
 *  into an infinite loop.
