 1.4 13-Feb-2009  he The attribute for if_le_oioc.c should apparently be le24, not le,
so that this file is not pulled into the GENERIC32_IP3x kernel,
where am7990.c isn't built.
 1.3 12-Feb-2009  rumble Enable Personal IRIS 4D/20 and 4D/25 support:
- Adapt int(4) to handle the INT1 chip
- Move generic rtc clocks out of hpc/ and into dev/
- Handle the very strangely wired eeprom and other bits in arcemu
- Sprinkle MACH_SGI_IP6 as necessary
- Enable IP6/IP10 devices in GENERIC32_IP12. Yes, the naming is poor but
there's no winning with kernel/hw compatibility on sgimips...

Tested on my 4D/25. Doesn't (appear to) break macallan@'s IP22.
 1.2 11-Dec-2005  christos branches: 1.2.78; 1.2.86; 1.2.92;
merge ktrace-lwp.
 1.1 15-Dec-2003  sekiya branches: 1.1.4;
Add dedicated IOC (I/O Controller) driver. pckbc, zstty, and lpt will each
receive *_ioc.c attachments; machines without IOC (i.e., IP20) will use *_hpc.c
stubs.

 1.6 12-Feb-2022  riastradh sys: Fix various abuse of struct device internals.

Will help to make struct device opaque later.
 1.5 11-Jun-2015  matt Add struct pmap_limits and pm_{min,max}addr from uvm/pmap/map.h and use it to
store avail_start, avail_end, virtual_start, and virtual_end.
Remove iospace and let emips just bump pmap_limits.virtual_start to get the
VA space it needs.
pmap_segtab.c is almost identical to uvm/pmap/pmap_segtab.c now. It won't
be long until we switch to the uvm/pmap one.
 1.4 20-Feb-2011  matt branches: 1.4.14; 1.4.32;
Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework
Deal with arcbios calls being O32 and kernels being N32/N64.
Need to save/restore T8 across arcbios calls.
 1.3 10-Jan-2011  tsutsui branches: 1.3.2; 1.3.4;
Use ether_aton_r() in sys/net/if_ethersubr.c instead of home grown copies.
Hint from ryo@. Tested on IP32 mec(4).
 1.2 19-Jan-2010  pooka branches: 1.2.4;
Redefine bpf linkage through an always present op vector, i.e.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

 1.12 24-Apr-2021  thorpej branches: 1.12.8;
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?).
 1.11 18-Feb-2015  macallan branches: 1.11.32;
switch sgimips to common bus_dma and bus_space in arch/mips/
Tested on O2 and Indy.
Things that are compile-tested only for lack of hardware:
- GIO ethernet cards with PCI bridges
- IP2x hardware not found on Indy
- IP1x
 1.10 27-Oct-2012  chs branches: 1.10.14;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".

 1.8 03-Mar-2009  macallan Comment out some register initialization which the firmware should have taken
care of anyway. Apparently doing this here disrupts newport's blitter
operations and causes a deadlock.
 1.7 17-Oct-2007  garbled branches: 1.7.20; 1.7.28; 1.7.30; 1.7.34; 1.7.38;
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.

 1.11.32.6 05-Apr-2021  thorpej Treat config_probe() as if it were a boolean function; don't compare
return value > 0... except for the odd balls, which are now really easy
to spot.
 1.11.32.5 05-Apr-2021  thorpej config_match() -> config_probe() for the straight-forward indirect config
cases. There are still a few odd balls using config_match() which should
be sorted out later.
 1.11.32.4 04-Apr-2021  thorpej CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
 1.11.32.3 03-Apr-2021  thorpej Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
 1.11.32.2 21-Mar-2021  thorpej CFARG_IATTR usage audit:

If a device carries only one interface attribute, there is no need
to specify it when calling config_search(); that specification is
meant only to disambiguate which interface attribute (which is a
proxy for "what kind of attach args are being used") is having
children attached. cfparent_match() will take care of ensuring that
any potential children can attach to one of the parent's iterface
attributes, and if the parent only carries one, no disambiguation is
necessary.
 1.11.32.1 20-Mar-2021  thorpej 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.
