4	* @brief Configuration Table Template that will be Instantiated
5	* by an Application
6	*
7	* This include file contains the configuration table template that will
8	* be instantiated by an application based on the setting of a number
9	* of macros. The macros are documented in the Configuring a System
10	* chapter of the Classic API User's Guide
11	*
12	* The model is to estimate the memory required for each configured item
13	* and sum those estimates. The estimate can be too high or too low for
14	* a variety of reasons:
15	*
16	* Reasons estimate is too high:
17	* + FP contexts (not all tasks are FP)
18	*
19	* Reasons estimate is too low:
20	* + stacks greater than minimum size
21	* + messages
22	* + application must account for device driver resources
23	* + application must account for add-on library resource requirements
24	*
25	* NOTE: Eventually this may be able to take into account some of
26	* the above. This procedure has evolved from just enough to
27	* support the RTEMS Test Suites into something that can be
28	* used remarkably reliably by most applications.

597	*
598	* By reducing the number of priorities in a system,

605	* 4 and 256. Valid values along with the application
606	* priority levels and memory saved when pointers are
607	* 32-bits in size are:
608	*
609	* + 3, 2 application priorities, 3024 bytes saved

611	* + 15, 13 application priorities, 2880 bytes saved
