 1.42  22-Jan-2022  thorpej Change the devhandle_from_*() functions to also take a "super handle",
from which the newly created handle will inherit it's implementation.
The root implementation for a new handle type is used if an invalid
"super handle" is passed.
 1.41  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.40  10-May-2021  thorpej branches: 1.40.4;
Associate the OpenBoot / OpenFirmware node with attached devices
at config_found() time.
 1.39  24-Apr-2021  thorpej branches: 1.39.2; 1.39.4;
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?).
 1.38  22-Nov-2020  thorpej branches: 1.38.2;
malloc(9) -> kmem(9) (easy, straight-forward cases only, for now)
 1.37  10-Nov-2019  chs branches: 1.37.8;
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.
 1.36  18-Oct-2019  msaitoh s/initalize/initialize/ in comment or printf message.
 1.35  18-Oct-2014  snj branches: 1.35.20;
src is too big these days to tolerate superfluous apostrophes. It's
"its", people!
 1.34  30-Jan-2012  mrg branches: 1.34.6;
avoid writing 1 byte beyond the end of the string promlib.c has given us.
instead of forcing a nul byte afterwards, KASSERT() that the final byte
already is a nul. if there are broken proms... well, we can fix them.

this, plus one more change, allows my SS20 to boot multiuser.
 1.33  18-Jul-2011  mrg branches: 1.33.2; 1.33.6;
convert the remaining sparc drivers to CFATTACH_DECL_NEW/cfdata_t/device_t.
(cgsix_obio.c was only partially converted with the rest of the cgsix code
when it was changed some time ago.)
 1.32  01-Jul-2011  dyoung #include <sys/bus.h> instead of <machine/bus.h>.
 1.31  20-Sep-2009  tsutsui - use device_t and cfdriver_t
- use device_private() and device_xname()
- use proper types or variables for device_t/softc
 1.30  29-May-2008  mrg remove clause #3 from my license where there are no other
copyright holders involved.
 1.29  17-Oct-2007  garbled branches: 1.29.16; 1.29.18; 1.29.20; 1.29.22;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.28  09-Jul-2007  ad branches: 1.28.10;
Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements
 1.27  04-Mar-2007  christos branches: 1.27.2; 1.27.4; 1.27.10;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.26  25-Feb-2007  uwe G/c debugging printf (hi, macallan!).
 1.25  02-Jul-2006  jdc branches: 1.25.10;
PCI device list and interrupt mapping for JavaStation Espresso.
Interrupt line values from Linux sparc sources.
 1.24  24-Nov-2005  he branches: 1.24.4; 1.24.8; 1.24.16;
Remove declaration of a variable which is no longer used.
 1.23  24-Nov-2005  he Make sure the file ends with a newline, so the port builds again.
 1.22  22-Nov-2005  macallan add support for options BLINK
 1.21  16-Nov-2005  uwe ANSIify. Use uint<N>_t. Drop unnecessary inlcudes.
Declare as static everything we don't need to export.
 1.20  12-Aug-2005  macallan branches: 1.20.6;
revert previous version, will create a device node in the boot loader instead
 1.19  12-Aug-2005  macallan For Krups only - attach audiocs at ebus even if there's no sound node in the
device tree. Works only as long as the cs4231 driver doesn't attempt to use
the node since we can't really supply one.
Tested on a Krups with OF 3.11.10
 1.18  10-Jul-2004  pk branches: 1.18.12;
Use bus_space_tag_alloc().
 1.17  24-Apr-2004  kleink Update for new pci_devinfo(9) signature.
 1.16  17-Mar-2004  pk Rename PROM_getprop*() => prom_getprop*().
 1.15  27-Aug-2003  mrg change PROM_getprop() from taking a "void **" for the storage, to a
"void *", and do the extra de-reference directly in the function. this
avoids having to cast dozens of different types to "void **", which sets
of GCC3's strict-aliasing. testing by martin@
 1.14  15-Jul-2003  lukem __KERNEL_RCSID()
 1.13  03-May-2003  wiz branches: 1.13.2;

 1.9  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.8  01-Oct-2002  thorpej Use CFATTACH_DECL().
 1.7  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.6  11-Mar-2002  uwe Do not pass bus type argument (R.I.P.) to bus_space_map2.
 1.5  11-Mar-2002  pk * `bus_type_t' is gone.
* Use BUS_ADDR() where appropriate to encode I/O space and physical
address offset into a `bus_addr_t' value.
* Drop obio_bus_map() since it's now completely equivalent to bus_space_map()
* Use bus_space_map2() to map device space at a fixed virtual address.
* Remove the virtual address argument from sbus_sbus_addr()
 1.4  18-Feb-2002  uwe Convert to use shared headers in dev/ebus. Move ebus_softc definition here.
Normalize bar field of EBus children PROM "reg" property to be the BAR
offset in PCI config space like on sparc64 when building ebus_attach_args.
