- * Implementation of "non-robust" Szymanski linear-waiting algorithm. Types of
- * failures tolerated by Szymanski's "robust" algorithm are not specific for
- * Xtensa DSP cluster and therefore more lightweight version of the algorithm
- * is used. FIFO servicing property is of low importance, and faster/smaller
- * version with linear-wait property is preferable.
- *
- * We assume there is just a single mutex in the system, and all communication
- * variables are defined somewhere in board-specific headers and imported here
- * by means of macros MUTEX_SHARED_READ/WRITE.
