 1.45  10-May-2023  riastradh pcmcom(4): Use config_detach_children.
 1.44  25-Sep-2022  thorpej Remove unnecessary include of <sys/malloc.h>.
 1.43  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.42  24-Apr-2021  thorpej branches: 1.42.8;
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?).
 1.41  08-Dec-2018  thorpej branches: 1.41.14;
Clean up initialization of com_regs structure, in preparation for
some additional changers.
 1.40  27-Oct-2012  chs branches: 1.40.36; 1.40.38;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.39  06-Dec-2009  dyoung branches: 1.39.12; 1.39.22;
device_t/softc split.
 1.38  12-Nov-2009  dyoung Don't use com_activate(), it's gone away. Delete superfluous
activation hook, pcmcom_activate().

Add a child-detachment hook and use it.

Use device_private().

Cosmetic: use __arraycount(). Join a couple of lines. Delete a
set of superfluous parentheses.
 1.37  12-May-2009  cegger struct device * -> device_t, no functional changes intended.
 1.36  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.35  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.34  28-Apr-2008  martin branches: 1.34.8; 1.34.14;
Remove clause 3 and 4 from TNF licenses
 1.33  05-Apr-2008  cegger branches: 1.33.2; 1.33.4;
use aprint_*_dev and device_xname
 1.32  14-Mar-2008  cube Split device_t and softc for all com(4) devices (well, everything that
uses a com_softc backend). Use proper types and ansify where appropriate.
 1.31  19-Oct-2007  ad branches: 1.31.12; 1.31.16;
machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h
 1.30  16-Nov-2006  christos branches: 1.30.8; 1.30.22; 1.30.24; 1.30.28;
__unused removal on arguments; approved by core.
 1.29  16-Nov-2006  christos non working dual serial port.
 1.28  12-Oct-2006  christos - sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386
 1.27  13-Jul-2006  gdamore branches: 1.27.4; 1.27.6;
Add an option COM_REGMAP to allow com(4) to use an array of register indices.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.

Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.

This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

Approved by core@. Fixes PR port-evbmips/32362.
 1.26  25-Mar-2006  thorpej branches: 1.26.4;
Use device_parent().
 1.25  11-Dec-2005  christos branches: 1.25.4; 1.25.6; 1.25.8; 1.25.10; 1.25.12;
merge ktrace-lwp.
 1.24  26-Aug-2005  drochner kill some more simple submatch() functions, use config_stdsubmatch()
 1.23  25-Aug-2005  drochner replace the "locdesc_t" structure carrying the number of locators
explicitely by a plain integer array
the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks
 1.22  27-Feb-2005  perry branches: 1.22.4;
nuke trailing whitespace
 1.21  04-Feb-2005  perry de-__P
 1.20  13-Sep-2004  drochner branches: 1.20.4; 1.20.6;
a round of autoconf cleanup:
-convert submatch() style functions (passed to config_search() or
config_found_sm()) to the locator passing variants
-pass interface attributes in some cases
-make submatch() functions look uniformly as far as possible
-avoid macros which just hide cfdata members, and reduce dependencies
on "locators.h"
 1.19  10-Aug-2004  mycroft Update to the new world order. While I'm here, simplify a lot.
 1.18  10-Aug-2004  mycroft Now that all the silly string printing is gone, move the location where we
print a newline so it doesn't have to be done in every driver.
 1.17  10-Aug-2004  mycroft Enhance pcmcia_product_lookup():
* Remove the "expected function" value. This was just causing problems with
multifunction cards. Differentiating the functions is better done by
checking the function type (which we now do in ep and sm).
* Add support for matching CIS strings. This necessitated changing the calling
pattern a little too.

Use this enhanced version rather than driver-specific versions that do the
same thing.

Also, remove the last vestiges of PCMCIA_STR_*.
 1.16  09-Aug-2004  mycroft Correct the intr_establish order here.
 1.15  08-Aug-2004  mycroft Remove the "offset" and "size" arguments to pcmcia_io_map(). In the singular
case (ne@pcmcia) where we were using these to create a subregion, it is better
handled by calling bus_space_subregion().

Now there is a 1:1 mapping between I/O spaces in the config table and windows
mapped in the function. Rework the multifunction mapping code to take
advantage of this by using both I/O base addresses if necessary.
 1.14  01-Jan-2003  thorpej branches: 1.14.2;
Use aprint_normal() in cfprint routines.
 1.13  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.12  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.11  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.10  27-Sep-2002  thorpej Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.
 1.9  01-Jun-2002  lukem SIMPLEQ rototill:
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
 1.8  12-Jan-2002  tsutsui branches: 1.8.8;
Call malloc(9) with M_ZERO flag instead of memset() after malloc().
 1.7  13-Nov-2001  lukem add RCSIDs
 1.6  24-May-2000  itojun branches: 1.6.6; 1.6.8;
correct pcmcom detach (like card removal). PR 9334.
 1.5  04-Feb-2000  cgd replace the *_lookup table entry match/lookup functions in all of
these drivers with a single common function (which supports tables
of variable-sized structures). Things are mostly as they were before:
tables are terminated by entry with NULL name, etc. There's also
the ability to call a driver-specific match function which can be used
to augment the table lookup.
 1.4  20-Nov-1998  thorpej branches: 1.4.10;
Detach children in reverse order. We are more likely to be able to recycle
cloned unit numbers that way.
 1.3  19-Nov-1998  thorpej Add support for hot-swapping PCMCIA serial devices.
 1.2  14-Oct-1998  thorpej Nuke spurious ;
 1.1  10-Oct-1998  thorpej Device driver for PCMCIA multi-port serial cards. Currently supports
the Socket Communications, Inc. dual-rs232 device.
 1.4.10.1  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
