84 * The model is to estimate the memory required for each configured item
85 * and sum those estimates.  The estimate can be too high or too low for
86 * a variety of reasons:
87 *
88 * Reasons estimate is too high:
89 *   + FP contexts (not all tasks are FP)
90 *
91 * Reasons estimate is too low:
92 *   + stacks greater than minimum size
93 *   + messages
94 *   + application must account for device driver resources
95 *   + application must account for add-on library resource requirements
96 *
97 * NOTE:  Eventually this may be able to take into account some of
98 *        the above.  This procedure has evolved from just enough to
99 *        support the RTEMS Test Suites into something that can be
100 *        used remarkably reliably by most applications.

640 * @brief Maximum priority configuration.
641 *
642 * This configures the maximum priority value that
643 * a task may have.
644 *
645 * The following applies to the data space requirements
646 * of the Priority Scheduler.
647 *
648 * By reducing the number of priorities in a system,
649 * the amount of RAM required by RTEMS can be significantly
650 * reduced.  RTEMS allocates a Chain_Control structure per
651 * priority and this structure contains 3 pointers.  So
652 * the default is (256 * 12) = 3K on 32-bit architectures.
653 *
654 * This must be one less than a power of 2 between
655 * 4 and 256.  Valid values along with the application
656 * priority levels and memory saved when pointers are
657 * 32-bits in size are:
658 *
659 *   + 3,  2 application priorities, 3024 bytes saved
660 *   + 7, 5 application priorities, 2976 bytes saved
661 *   + 15, 13 application priorities, 2880 bytes saved
662 *   + 31, 29 application priorities, 2688 bytes saved
663 *   + 63, 61 application priorities, 2304 bytes saved
664 *   + 127, 125 application priorities, 1536 bytes saved
665 *   + 255, 253 application priorities, 0 bytes saved
666 *
667 * It is specified in terms of Classic API priority values.

688 *  - CONFIGURE_SCHEDULER_EDF - EDF Scheduler

693 * If no configuration is specified by the application in a uniprocessor
