 1.21  01-May-2025  tsutsui Use uint32_t instead of u_int32_t.
 1.20  08-Oct-2023  andvar branches: 1.20.6;
Update __BS_TYPENAME(BITS) macro to combine uint type instead of u_int.
Constify bus_space_write_multi one of params.
Remove unused ic_intr property from mipsco_isa_chipset struct.
Add __INTR_PRIVATE definition to mipsco isa_machdep.c.

Fixes RC3230 mipsco kernel config (w/o KGDB option, will be addressed later).
 1.19  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.18  24-Apr-2021  thorpej branches: 1.18.8;
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?).
 1.17  21-Nov-2020  thorpej branches: 1.17.2;
malloc(9) -> kmem(9)
 1.16  10-Nov-2019  chs branches: 1.16.8;
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.
 1.15  27-Oct-2012  chs branches: 1.15.38;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.14  19-Aug-2009  dyoung branches: 1.14.12; 1.14.22;
isa_detach_hook() needs two arguments, the first an isa_chipset_tag_t.
 1.13  18-Aug-2009  dyoung These are stragglers from my last commit ("Let us safely detach
the ISA bus and devices attaching to the ISA bus"). Define
isa_detach_hook() in MD ISA implementations. Define isa_dmadestroy().
 1.12  16-Mar-2009  dsl ANSIfy functions with function-pointer arguments
 1.11  14-Mar-2009  dsl ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
 1.10  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.)
 1.9  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.8  28-Apr-2008  martin branches: 1.8.8; 1.8.14;
Remove clause 3 and 4 from TNF licenses
 1.7  11-Dec-2005  christos branches: 1.7.74; 1.7.76; 1.7.78;
merge ktrace-lwp.
 1.6  30-Aug-2004  drochner Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.
 1.5  15-Jul-2003  lukem __KERNEL_RCSID()
 1.4  02-Oct-2002  thorpej branches: 1.4.6;
Use CFATTACH_DECL().
 1.3  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.2  02-Apr-2001  wdk branches: 1.2.2; 1.2.4; 1.2.10;
Clear interrupt latch after interrupts are processed, not before.
 1.1  30-Mar-2001  wdk Support for ISA expansion slot in Mips 3230

The ISA Bus on this machine doesn't support DMA, and all interrupt lines
are wire-OR'ed together. Mileage may vary if sharing interrupts.

Tested cards:
com: 8250 and 16550 UART's (8 bit)
ec: 3com Etherlink II (8 bit)
we: SMC 8013 Ethernet (16 bit) [work in progress]
Probes, ARP in both directions works, sends clean packets,
tcpdump show correct packets on receive, NDP for IPv6 works,
netstat -s shows nothing strange.. but doesn't talk TCP/IP!
