91998fc549 Spring forward into the late 1970's by following item 5 in the yacc
manual's Appendix D ("Old Features Supported but not Encouraged") in
the Seventh Edition Unix Programmer's Manual (January, 1979) by
retiring the " = {" method of of action specification in favor of a
plain "{".  It is no longer necessary for this bootstrap program to
be compatible with 6th Edition systems.  Some yaccs in the wild do not
support this old syntax any more, and compatibility with those systems
is more important these days (as there are easily 7 orders of magnitude
more of them than real v6 systems today).

c1f4dd9355 Fix some problems that affect multiple file inclusion. Bruce found
this bug and submitted these patches to dunstan@.  He sent them to me
to test, and I discovered they were needed for the atmel kernel config
files.  Since we were playing with them in the terminal room after the
developer's summit today, I thought I'd go ahead and commit them to
allow those folks that now have atmel hardware (thanks Andre) a chance
to try it out w/o my help.  Since dunstan@ is asleep right now, risk
stepping on his toes a little by going ahead and committing this
change.

744b947ef8 Improve INCLUDE_CONFIG_FILE support.
This change will let us to have full configuration of a running kernel
available in sysctl:

	sysctl -b kern.conftxt

The same configuration is also contained within the kernel image. It can be
obtained with:

	config -x <kernelfile>

Current functionality lets you to quickly recover kernel configuration, by
simply redirecting output from commands presented above and starting kernel
build procedure. "include" statements are also honored, which means options
and devices from included files are also included.

Please note that comments from configuration files are not preserved by
default. In order to preserve them, you can use -C flag for config(8). This
will bring configuration file and included files literally; however,
redirection to a file no longer works directly.

dfdbf9be00 Optionally include a DEFAULTS config file if it is present in the current
directory before the specified config file.  This is implemented by
opening DEFAULTS as stdin if it exists, and if so resetting stdin to the
actual config file when DEFAULTS is fully parsed via yywrap().  In short,
this lets us create DEFAULTS kernel configs in /sys/<arch>/conf that can
enable certain options or devices by default and allow users to disable
them via 'nooptions' or 'nodevice' rather than having to create kludge
NO_FOO options.

f37a929ca1 Kill count device support from config. I've changed the last few
remaining consumers to have the count passed as an option.  This is
i4b, pc98/wdc, and coda.

Bump configvers.h from 500013 to 600000.

Remove heuristics that tried to parse "device ed5" as 5 units of the ed
device.  This broke things like the snd_emu10k1 device, which required
quotes to make it parse right.  The no-longer-needed quotes have been
removed from NOTES, GENERIC etc.  eg, I've removed the quotes from:
   device  snd_maestro
   device  "snd_maestro3"
   device  snd_mss

I believe everything will still compile and work after this.

e3937b620a Fixed spurious syntax errors for including files that don't begin with
a SEMICOLON token (a newline or semicolon, or one of these preceded
by a comment and/or whitespace).  The input stream was switched too
early and the parser was expecting a SEMICOLON in the included file
instead of after the filename in the include directive.

824018495d Implemented "nooption" and "nomakeoption" config(8) tokens.
Fixed memory leak in the "nodevice" option implementation.

Use these instead of sed(1) in MD NOTES.

Use a single makefile (sys/conf/makeLINT.mk) to generate
LINT for all architectures.  (Previous versions missed
the LINT dependency on Makefile, and i386 version also
missed the dependency on ${NOTES}.)

Fixed bugs in the previous NOTES conversion using the
"nodevice" token and sed(1):

- i386 LINT lost "device pst".

- pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD
  options, and got needless DPT_* options.

- Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV
  to sparc64 LINT so that it has a chance to config(8).

This basically returns us to where we were before.

5e06480c9f Introduce an "include" directive. It takes one argument, a filename
to be included into this one.  This works the same way as #include
does in C; as far as the user is concerned, the included file is
inlined into the current one.

Since config(8) is no longer limited to working on one user-supplied
file, printing just a line number in an error message is not
sufficient.  The new global variable yyfile represents the file
currently being parsed, and must be printed as well.

f71c01cc52 Borrow phk's axe and apply the next stage of config(8)'s evolution.
Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel.  You can reconfigure your
isa devices with the likes of this at loader(8) time:
  set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8).  See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8).  There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file.  If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you.  You can also compile in the
hints directly with:  hints "device.hints"  as well.

There are a few things that I'm not too happy with yet.  Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it.  However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built.  A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated.  eg:  'device fe 4' will compile the fe driver with NFE set
to 4.  You can then set hints for 4 units (0 - 3).  Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this.  This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

218f95f38b Clean up something in config(8) that has annoyed me for ages. Remove
the need to specify the unit number of unwired devices.  ie: instead
of saying "device fxp0" we can say "device fxp" which is much closer
to what it actually means.  The former (fxp0) implied something about
reserving the 0th unit, but it does not and never did - it was a
figment of config(8)'s imagination that we had to work around..
"device fxp0" simply means "compile in the fxp device driver", so we
may as well just write it as "device fxp" which is closer to what it
really means.

Doing this also saves us from filling up the ioconf.c tables with
meaningless entries.

9414269597 Apply the axe to some more cruft in config(8). In particular:
- redo the "at" configuration system so that it just syntax checks
  to make sure the device you're configuring something "at" appears to
  exist.  Nuke a bunch of complexity that was responsible for creating
  "clones" of wildcard devices and some wierd stuff in a few places
  including the scbus config tables etc.
- merge "controller" and "device" - there is no difference as far as
  the kernel is concernend, it's just something there to make life
  difficult for config file writers.  "controller" is now an alias for
  "device".
- emit full scsi config into the resource tables.  We could trivially
  change cam to use that rather than it's own "special" table for wiring
  and static configuration.  ATA could use this too for static wiring.
- try and emulate some of the quirks of the old system where it made
  sense.  Some were too strange though and I'd be very suprised if they
  were features and not outright bugs.  nexus handling is still strange.
  One thing in particular is that some of the wierd entries in the
  newbus devtables is now gone as it was a quirk side effect of the
  wildcard/question-mark cloning above.

GENERIC and LINT still build etc.
