/**
 * @file rtems/confdefs.h
 *
 *  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.

 *
 *  This configures the maximum priority value that

 *
 *  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
