* 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.

* 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
