-Smart CONFIG_* Dependencies
-1 August 1999
-Michael Chastain   <mec@shout.net>
-Werner Almesberger <almesber@lrc.di.epfl.ch>
-Martin von Loewis  <martin@mira.isdn.cs.tu-berlin.de>
-Here is the problem:
-    Suppose that drivers/net/foo.c has the following lines:
-        #include <linux/config.h>
-        ...
-        #ifdef CONFIG_FOO_AUTOFROB
-            /* Code for auto-frobbing */
-        #else
-            /* Manual frobbing only */
-        #endif
-        ...
-        #ifdef CONFIG_FOO_MODEL_TWO
-            /* Code for model two */
-        #endif
-    Now suppose the user (the person building kernels) reconfigures the
-    kernel to change some unrelated setting.  This will regenerate the
-    file include/linux/autoconf.h, which will cause include/linux/config.h
-    to be out of date, which will cause drivers/net/foo.c to be recompiled.
-    Most kernel sources, perhaps 80% of them, have at least one CONFIG_*
-    dependency somewhere.  So changing _any_ CONFIG_* setting requires
-    almost _all_ of the kernel to be recompiled.
-Here is the solution:
-    We've made the dependency generator, mkdep.c, smarter.  Instead of
-    generating this dependency:
-        drivers/net/foo.c: include/linux/config.h
-    It now generates these dependencies:
-        drivers/net/foo.c: \
-            include/config/foo/autofrob.h \
-            include/config/foo/model/two.h
-    So drivers/net/foo.c depends only on the CONFIG_* lines that
-    it actually uses.
-    A new program, split-include.c, runs at the beginning of
-    compilation (make bzImage or make zImage).  split-include reads
-    include/linux/autoconf.h and updates the include/config/ tree,
-    writing one file per option.  It updates only the files for options
-    that have changed.
-Flag Dependencies
-    Martin Von Loewis contributed another feature to this patch:
-    'flag dependencies'.  The idea is that a .o file depends on
-    the compilation flags used to build it.  The file foo.o has
-    its flags stored in .flags.foo.o.
-    Suppose the user changes the foo driver from resident to modular.
-    'make' will notice that the current foo.o was not compiled with
-    -DMODULE and will recompile foo.c.
-    All .o files made from C source have flag dependencies.  So do .o
-    files made with ld, and .a files made with ar.  However, .o files
-    made from assembly source do not have flag dependencies (nobody
-    needs this yet, but it would be good to fix).
-Per-source-file Flags
-    Flag dependencies also work with per-source-file flags.
-    You can specify compilation flags for individual source files
-    like this:
-        CFLAGS_foo.o = -DSPECIAL_FOO_DEFINE
-    This helps clean up drivers/net/Makefile, drivers/scsi/Makefile,
-    and several other Makefiles.
-Credit
-    Werner Almesberger had the original idea and wrote the first
-    version of this patch.
-    
-    Michael Chastain picked it up and continued development.  He is
-    now the principal author and maintainer.  Please report any bugs
-    to him.
-    Martin von Loewis wrote flag dependencies, with some modifications
-    by Michael Chastain.
-    Thanks to all of the beta testers.
