/** @file
 *
 * Configuration options
 *
 * This file contains macros that pull various objects into the link
 * based on definitions in configuration header files. Ideally it
 * should be the only place in iPXE where one might need to use #ifdef
 * for compile-time options.
 *
 * In the fairly common case where an object should only be considered
 * for inclusion if the subsystem it depends on is present, its
 * configuration macros should be placed in a file named
 * <tt>config_<i>subsystem</i>.c</tt>, where @e subsystem is the
 * object basename of the main source file for that subsystem. The
 * build system will pull in that file if @c subsystem.c is included
 * in the final iPXE executable built.
