/**
* @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.
