sys: Split struct device into a private device_impl.h.

Include this only inside autoconf itself, and a few files that abuse
autoconf in ways I can't confidently make easy fixes for.

XXX kernel ABI change requires bump -- no more use of struct device
internals allowed, previously done by some drivers

Merge thorpej-cfargs2.

Adapt to CFARGS().

Sync with HEAD.

The Amiga and Atari ports abuse some autoconfiguration internals as part
of their early console bring-up, so we need to expose some of the new
internals to them and adapt the call sites.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
  actually needed.
- Don't be explicit about what interface attribute is attaching if
  the device only has one.  (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
  situations, making is visibly easier to see when indirect config is
  in play, and allowing for future change in semantics.  (As of now,
  this is just a wrapper around config_match(), but that is an
  implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance.  This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Sync with HEAD.

Give config_found() the same variadic arguments treatment as
config_search().  This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls.  Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.

The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:

- Introduce a new cfarg_t enumerated type, that defines the types of
  tag-value variadic arguments that can be passed to the various
  config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
  for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
  variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
  Noticed several incorrect usages along the way, which will be
  audited in a future commit.

malloc(9) -> kmem(9)

Mostly merge changes from HEAD upto 20200411

Make local functions static.

Sync with HEAD

Make sure interrupts are disabled during cpu_configure(9).

Fixes 'panic: kernel diagnostic assertion "cv_is_valid(cv)" failed'
during fdcisa(4) probe on Milan's DIAGNOSTIC kernel, caused by
a stray interrupt from the FDC right after isa_intr_establish().
No visible bad side effect on TT030 with this change.

Should be pulled up to netbsd-8.

At suggestion of chuq@, modify config_attach_pseudo() to return with a
reference held on the device.

Adapt callers to expect the reference to exist, and to ensure that the
reference is released.

Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).

The branch now builds, and installs via anita.  There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.

Adapt the machine/arch dependent code to the new {b,c}devsw reference
counting.

XXX Most of these will require testing by someone other than myself, as
I have a limited selection of hardware!

Rebase to HEAD as of a few days ago.

Add a dirty hack for atari's ancient installation ramdisk:
 Forcibly configure md0, md1, and md2 devices before setroot()
 for atari's traditional "auto-load from floppy on open" md_root device
 which loads installation ramdisk image from floppy.
 md(4) has been changed dynamically configured at first open after 5.0
 and md devices won't appear in "root device:" prompt without this hack.
Tested on TT030.
Should be pulled up to netbsd-6.
Make sure that disklabel of md(4) device is initialized
in the case where it's configured in MD md_open_hook().
Without this, msdosfs_mountfs() (which is called from msdosfs_mountroot())
will be called with uninitialized disklabel (d_secsize == 0) and
it gets "panic: buf mem pool index 23" later on atari.
This is because getdisksize() doesn't check returned d_secsize value
and msdosfs_mountfs() blindly calls bread(9) with size==0 in that case.
Should be pulled up to netbsd-6 (at least for atari).
Add a sanity check if secsize returned from getdisksize() isn't bogus.
This prevent possible panic "panic: buf mem pool index 23" later in
vfs_bio.c:buf_mempoolidx().
(I'm not sure if it's okay for getdisksize() to assume that
 partinfo taken from DIOCGPART is properly initialized
 on all disk(9) devices or not)

Added NE2000 with 8bit bus width support.
reviewd by tsutsui@ at tech-kern ML.
Fix a wrong calculation bug around RX ring buffer memory address
slipped in about sixteen years ago.  Fortunately, it had been working
for ages because some devices used address zero and other devices
ignored wrong higher bits.
Tested on we(4) (SMC Elite Ultra) and ne(4) (NE2000 compatible
named UL0001) on ISA.
Note FreeBSD also uses the same correct value in their ed(4) driver.
Now dp8390_config() calculates mem_ring correctly so
no longer need to override it in ne2000_attach().
Use roundup2() in <sys/param.h> rather than a conditional.
Also fix a wrong mem_ring calculation in dp8390_ipkdb_attach().
Put several fixes to ne(4) driver for better 8 bit mode support,
especially on RTL8019AS which is also used for non-ISA local bus of
embedded controllers and some m68k machines like atari and x68k.
 * move RTL8019 probe and attach code from each bus attachment
   to MI ne2000_detect() and ne2000_attach()
 * change a method for backend and attachment to specify 8 bit mode
   to use a new sc->sc_quirk member, instead of sc->sc_dmawidth
 * handle more NE2000 8 bit mode specific settings, including
   bus_space(9) access width and available size of buffer memory
 * add a function to detect NE2000 8 bit mode
   (disabled by default, but enalbed by options NE2000_DETECT_8BIT
    to avoid possible regression on various ISA clones)
 * fix ipkdb attachment accordingly (untested)
Tested on two NE2000 ISA variants (RTL8019AS and another clone named UL0001)
in both 8 bit and 16 bit mode on i386. "Looks good" from nonaka@.
See my post on tech-kern for details:
http://mail-index.NetBSD.org/tech-kern/2010/02/26/msg007423.html
No need to override mem_ring value in ne2000_ipkdb_attach()
since a wrong calculation in dp8390_ipkdb_attach() was fixed.
Don't warn about DMA timeout during probe.

Add use of __UNCONST() when passing a constant string to some of the

Make things work with the new autoconf stuff:

  Otherwise we end up without a console.

sync kqueue with -current; this includes merge of gehenna-devsw branch,

Overhaul the way cfattach structures are looked up.  The cfdata entry
now carries the name of the attachment (e.g. "tlp_pci" or "audio"),
and cfattach structures are registered at boot time on a per-driver
basis.  The cfdriver and cfattach pointers are cached in the device
structure when attached.

Use CFATTACH_DECL().

Add a config_init() function to initialize the config data structures.
Normally this is called by configure(), but some ports (amiga, atari,
x68k) need to do this early because of how they find the console.

Declare all cfattach structures const.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Replace the access to devsw table and the hard-coded major with devsw API.

Convert all remaining devices.

A i386 GENERIC kernel compiles without the siop, ahc and bha drivers

siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Move config_console() out of the grf-layer. This allows for more than just
grf-type consoles (wscons). Config_console() is now called from consinit(),
just after setting up the kernel msgbuf, so debugging is easy(er).
To further facilitate this move, the pcibus now allows for early-console
attaches by allocating static bus_space_tags (no mallocs possible at this
point).

	  type.
	- Root file system type can be wildcarded; a machine-independent
	  function will try all possible file systems for the selected
	  root device until one succeeds.
	- If the root file system fails to mount, the operator will
	  be given the chance to select a new root device and file
	  system type, rather than having the machine simply panic.
	- nfs_mountroot() no longer panics if any part of the NFS
	  mount process fails; it now returns an error, giving the
	  operator a chance to recover.
	- New, more consistent, config(8) grammar.  The constructs:

		config netbsd swap generic
		config netbsd root on nfs

	  have been replaced with:

		config netbsd root on ? type ?
		config netbsd root on ? type nfs

	  Additionally, the operator may select or wildcard root file
	  system type in the kernel configuration file:

		config netbsd root on cd0a type cd9660

	  config(8) now requires that a "root" specification be
	  made.  "root" may be wired down or wildcarded.  "swap" and
	  "dump" specifications are optional, and follow previous
	  semantics.

	- config(8) has a new "file-system" keyword, used to configure
	  file systems into the kernel.  Eventually, this will be used
	  to generate the default vfssw[].

	- "options NFSCLIENT" is obsolete, and is replaced by
	  "file-system NFS".  "options NFSSERVER" still exists, since
	  NFS server support is independent of the NFS file system
	  client.

	- sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and
	  will be removed; all information is now generated by config(8).

As of this commit, all ports except arm32 have been updated to use
the new setroot().  Only SPARC, i386, and Alpha ports have been
tested at this time.  Port masters should test these changes on their
ports, and report any problems back to me.

More changes are on their way, including RB_ASKNAME support in
nfs_mountroot() (to prompt for server address and path) and, potentially,
the ability to select rarp/bootparam or bootp in nfs_mountroot().

Get rid of BROKEN_INDIRECT_CONFIG

backout previous kprintf changes

- Fix configuration name of 'lpt'
- add 'pcibus' as a mainbus device.

printf -> kprintf, sprintf -> ksprintf

Second arg to print function is now 'const char *'

change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

Yet more prototyping and -Wall fixes.

update for the fact that config_found() and config_rootfound() now
return pointers.  (Check vs. NULL, rather than just boolean tests.)

Another bit of prototyping...

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.

Switch to the mi ramdisk driver.

First bunch of changes due to stricter prototype checking.

Add an nvram-driver. This driver makes it possible to read/write the
configuration info stored in the nvram on the mc146818.

Dumping works, now if there were tools to handle it...
