 /**
- * @brief Maximum priority configuration.
- *
- * This configures the maximum priority value that
- * a task may have.
- *
- * The following applies to the data space requirements
- * of the Priority Scheduler.
- *
- * By reducing the number of priorities in a system,
- * the amount of RAM required by RTEMS can be significantly
- * reduced.  RTEMS allocates a Chain_Control structure per
- * priority and this structure contains 3 pointers.  So
- * the default is (256 * 12) = 3K on 32-bit architectures.
- *
- * This must be one less than a power of 2 between
- * 4 and 256.  Valid values along with the application
- * priority levels and memory saved when pointers are
- * 32-bits in size are:
- *
- *   + 3,  2 application priorities, 3024 bytes saved
- *   + 7, 5 application priorities, 2976 bytes saved
- *   + 15, 13 application priorities, 2880 bytes saved
- *   + 31, 29 application priorities, 2688 bytes saved
- *   + 63, 61 application priorities, 2304 bytes saved
- *   + 127, 125 application priorities, 1536 bytes saved
- *   + 255, 253 application priorities, 0 bytes saved
- *
- * It is specified in terms of Classic API priority values.

- *  @ingroup Configuration
- *
- * The scheduler configuration allows an application to select the
- * scheduling policy to use.  The supported configurations are:
- *
- *  - CONFIGURE_SCHEDULER_PRIORITY - Deterministic Priority Scheduler
- *  - CONFIGURE_SCHEDULER_PRIORITY_SMP - Deterministic Priority SMP Scheduler
- *  - CONFIGURE_SCHEDULER_PRIORITY_AFFINITY_SMP - Deterministic
- *    Priority SMP Affinity Scheduler
- *  - CONFIGURE_SCHEDULER_STRONG_APA - Strong APA Scheduler
- *  - CONFIGURE_SCHEDULER_SIMPLE - Light-weight Priority Scheduler
- *  - CONFIGURE_SCHEDULER_SIMPLE_SMP - Simple SMP Priority Scheduler
- *  - CONFIGURE_SCHEDULER_EDF - EDF Scheduler
- *  - CONFIGURE_SCHEDULER_EDF_SMP - EDF SMP Scheduler
- *  - CONFIGURE_SCHEDULER_CBS - CBS Scheduler
- *  - CONFIGURE_SCHEDULER_USER  - user provided scheduler
- *
- * If no configuration is specified by the application in a uniprocessor
- * configuration, then CONFIGURE_SCHEDULER_PRIORITY is the default.
- *
- * If no configuration is specified by the application in SMP
- * configuration, then CONFIGURE_SCHEDULER_PRIORITY_SMP is the default.
- *
- * An application can define its own scheduling policy by defining
- * CONFIGURE_SCHEDULER_USER and the following:
- *
- *    - CONFIGURE_SCHEDULER
- *    - CONFIGURE_SCHEDULER_TABLE_ENTRIES
- *    - CONFIGURE_SCHEDULER_USER_PER_THREAD
