jonathan 0925cf4fda Stronger checking of options:
* machinery for nonfatal warnings.
* new backend config-file keywords:
     defparam -- like defopt, but each defparam option is required
		 to have a value when configured via "options".
     defflag -- like defopt, but defflag options may not have a value.
		 Also, on "option FOO",  a needs-count style flag
		 (NFOO, either 0 or 1)  is emitted to the .h file.

* Warn about old-style options that aren't defined via def{opt,param,flag}
  and which are  added to IDENT. (These behave subtly differently
  to defopt options when  no explicit value is given.)

scottr e6eb7d0530 Implement option dependencies as part of the defopt action. We currently
restrict depended-on (or "implied") options to those that have been
previously defopt'ed, which inherently eliminates any cycles in the option
graph.

thorpej d12d850cfe Add a "deffs" keyword, similar to "defopt", that defines file systems.
Only things defined with this keyword will be allowed on "file-system"
lines in the kernel config files.

By default, -D... directives for file systems are not generated, since
they are not needed for most file systems now that vfs_conf.c is gone.
However, some file systems must have dependencies generated on them
(e.g. NFS, UNION).  So, provide a way to specify an option file for
these file systems.

thorpej ea4d1b7ea1 Rather than using a separate "class" keyword, treat device classes like
special attributes.  From Chris Demetriou.

thorpej bc1733bc88 Add code to emit the cfdriver structures into ioconf.c. This requires
a change to the config grammar, to specify a device's class (i.e. DV_xxx)
like:

device	sd class disk: ...

Also emit an ioconf.h, which contains extern declarations of the
cfdriver structures.

While I'm here, add support for specifying multiple options per defopt
line, as well as specifying the file name in which the options will
appear.

defopt	foo bar baz

generates "opt_foo.h", "opt_bar.h", and "opt_baz.h"

defopt	opt_mumble.h foo bar baz

generates "opt_mumble.h" which contains all three options.

Also, clean up and fix some bugs in the code that generates header files.

mycroft e8f7fd90c1 Actually, punt the `library' keyword; it does the same thing as `object',
and we really only need one of them.

mycroft 7d58ce9471 Add `object' and `library' keywords to pull in precompiled .o and .a files.
Syntax is like the `file' keyword; e.g.:
object	arch/i386/i386/mumble.o		[mumble] [needs-flag]
Largely from Michael Richardson in PR 3833, with some changes by me.

mrg 7d9c89b0ce remove "swap" configuration. 1997-06-12 15:03:09 +00:00
thorpej e14a0d029f Add support for generating "option headers". These allow options to
be included in object dependencies.  config(8) is told to generate
a header for a particular option with the new "defopt" keyword, used
in the files.* system description files.  Options that are placed in
header files are not given -D... cpp flags.

This approach allows options to be turned into headers incrementally,
rather than all at once, and allows for non-header options, as well.

thorpej 07c71aa7f7 Implement new grammar and semantics for specifying file systems
and the root device:

- New "file-system" keyword is used to configure file systems into
  the kernel.
- New way of specifying root device, which allows root file system
  type to always be specified.  Examples:

	config gennetbsd swap generic
	config sdnetbsd root on sd0a swap on sd0b
	config nfsnetbsd root on nfs

  are replaced by:

	config gennetbsd root on ? type ?
	config sdnetbsd root on sd0a type ffs swap on sd0b
	config nfsnetbsd root on ? type nfs
	config lenetbsd root on le0 type nfs

  Note that specific network interfaces may now be specified as
  the root device.
- swapgeneric.c is no longer used; generate a swap*.c file for each
  "config" line in the kernel configuration file.

gwr a0b75afc0b * Eliminate all shift/reduce conflicts in the grammar. This
requires that some ordering requirements are checked by the
  back-end C code instead of the parser (dirspecs, maxpart).

* Be more careful to require newline tokens in the grammer where
  they are expected, and deal with blank lines, etc.  This allows
  elimination of a trailing context on newline in the scanner.

* Let the parser set values for "needs-count" and "needs-flag"
  instead of making those special cases in the scanner.

* Get rid of '= ' preceeding actions (obsolete yacc syntax)

* Make the scanner not insert an extra newline after includes.
  (It was just an accidental side-effect of the ENDFILE stuff.)

actually used any more.

thorpej cb6211e540 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.
