 1.48  06-May-2023  andvar s/regster/register/ in comments and error messages.
 1.47  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.46  22-May-2021  thorpej branches: 1.46.4;
Be explicit about our interface attributes.
 1.45  24-Apr-2021  thorpej branches: 1.45.2; 1.45.4;
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?).
 1.44  21-Nov-2020  thorpej branches: 1.44.2;
malloc(9) -> kmem(9)
 1.43  10-Nov-2019  chs branches: 1.43.8;
in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.
 1.42  27-Oct-2012  chs branches: 1.42.38;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.41  18-Mar-2009  cegger branches: 1.41.12; 1.41.22;
Ansify function definitions w/o arguments. Generated with sed.
 1.40  11-Dec-2005  christos branches: 1.40.78; 1.40.86; 1.40.92;
merge ktrace-lwp.
 1.39  15-Jul-2003  lukem __KERNEL_RCSID()
 1.38  02-Oct-2002  thorpej branches: 1.38.6;
Use CFATTACH_DECL().
 1.37  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.36  27-Sep-2002  provos remove trailing \n in panic(). approved perry.
 1.35  03-May-2002  takemura Fixed debug print.
 1.34  10-Feb-2002  takemura Made vrgiu.c combilable without SINGLE_VRIP_BASE macro.
 1.33  09-Feb-2002  sato access GIUIOSEL_REG and GIUINTEN_REG
only if these registers are not GIU_NO_REG_W.
 1.32  02-Feb-2002  takemura Removed __vrcmu_supply() and __vrgiu_out(), which are need to enable serial
port before auto configuration.

Boot loaders (pbsdboot and hpcboot) are responsible to enable the port because
the kernel can't enable serial port for console any more.
 1.31  29-Jan-2002  uch clean up debug print and configuration.
 1.30  27-Jan-2002  takemura Added vripif.
 1.29  26-Jan-2002  takemura Straightened vripvar.h
 1.28  29-Dec-2001  takemura Added debugging output indicating details of interrupt register setting.
 1.27  16-Dec-2001  takemura BUGFIX: it gets bus error on Vr4122 and Vr4131 attempting to access
pull-up/pull-down registers if you turn on verbose output.
And moved softc structure definition from vrgiuvar.h to vrgiu.c, which was
needless in other parts of kernel.
 1.26  16-Sep-2001  uch branches: 1.26.4;
ANSIfy, KNF.
 1.25  07-Sep-2001  sato VR4131 have same restriction as VR4122.
 1.24  18-May-2001  enami branches: 1.24.2; 1.24.4;
Don't touch GIU{USE,TERM}UPDN_REG_W if ONLY_VR4122 is defined.
XXX ... for now. better way is needed.
 1.23  09-May-2001  shin don't define TAILQ_EMPTY here. TAILQ_EMPTY is defined in <sys/queue.h>.
 1.22  06-May-2001  takemura Vrc4172 GPIO support. This device is currently configured on PenCentra 130.
 1.21  01-May-2001  takemura Fix 'busname' to attach nodes correctly.
 1.20  30-Apr-2001  takemura Machine independent GPIO interface.
 1.19  21-Apr-2001  sato dump io setting: DPRINTF->VPRINTF
 1.18  18-Apr-2001  sato - support VR4122 vrip register map.
- support VR4122 ICU register map.
- support VR4122 intr levels.
XXX: currently if 'options VR4122' is defined,
XXX: cannot specify 'options VR4121','options VR4111', 'options VR4102'.
XXXX: i have not the VR4122 based hardware.. so no check for VR4122.
 1.17  27-Dec-2000  sato branches: 1.17.2;
-rewite codes by using new CONFIG_HOOK_SET and CONFIG_HOOK_EVENT.
 1.16  03-Oct-2000  sato flash led when intrrupt.
 1.15  25-Sep-2000  sato #include <sys/reboot.h> would probably suffice for those.
 1.14  25-Sep-2000  sato - add debug/verbose functions.
 1.13  25-Sep-2000  sato - can compile these files.
#include <sys/boot_flag.h>
 1.12  24-Sep-2000  jdolecek add new macro BOOT_FLAG() (defined in <sys/boot_flag.h>) - this
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate

as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro

for hpcmips, use new bootverbose instead of it's own hpcmips_verbose

Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.
 1.11  20-Jul-2000  deberg don't define TAILQ_FOREACH, it's in sys/queue.h now.
 1.10  03-Apr-2000  sato branches: 1.10.4;
- hpcmips_verbose
- pbsdboot -v option
- WIN I/O setting
- vrisa IRQ GPIO mapping
- memory banks.

 1.7  10-Mar-2000  sato fix print message when #undef VRGIUDEBUG and change a little.
 1.6  22-Feb-2000  sato delete warning.
 1.5  27-Jan-2000  sato - fix using uninitialized argument of bitdisp64().
 1.4  23-Dec-1999  takemura New button handler and power controller with configurable hooking mechanism.
 1.3  04-Dec-1999  takemura Print input/output/interrupt settings.

 1.1.1.1.2.1  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.
