/**
 * @file
 *
 * @brief Configuration Table Template that will be Instantiated
 * by an Application
 *
 * This include file contains the configuration table template that will
 * be instantiated by an application based on the setting of a number
 * of macros.  The macros are documented in the Configuring a System
 * chapter of the Classic API User's Guide
 *
 * The model is to estimate the memory required for each configured item
 * and sum those estimates.  The estimate can be too high or too low for
 * a variety of reasons:
 *
 * Reasons estimate is too high:
 *   + FP contexts (not all tasks are FP)
 *
 * Reasons estimate is too low:
 *   + stacks greater than minimum size
 *   + messages
 *   + application must account for device driver resources
 *   + application must account for add-on library resource requirements
 *
 * NOTE:  Eventually this may be able to take into account some of
 *        the above.  This procedure has evolved from just enough to
 *        support the RTEMS Test Suites into something that can be
 *        used remarkably reliably by most applications.

 * @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.
