 1.12  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.11  24-Apr-2021  thorpej branches: 1.11.8;
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?).
 1.10  06-Jul-2020  rin branches: 1.10.4;
Style and cosmetic changes. No binary changes intended.
 1.9  23-Jan-2012  phx Insert some missing aprint_naive().
 1.8  01-Jul-2011  dyoung branches: 1.8.2; 1.8.6;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.7  30-Jun-2011  matt Modify mapiodev to take a third argument indicating whether the space
should be prefetchable (true) or not (false).
 1.6  17-Jun-2011  matt struct device * -> device_t
struct cfdata * -> cfdata_t
split device/softc (CFATTACH_DECL_NEW)
use device_accessors and device_private
constify
 1.5  06-Jun-2011  matt More device_t, cfdata, CFATTACH_DECL_NEW cleanup.
 1.4  28-Apr-2008  martin branches: 1.4.22; 1.4.32;
Remove clause 3 and 4 from TNF licenses
 1.3  28-Jan-2008  garbled branches: 1.3.6; 1.3.8; 1.3.10;
Apparently BRIDGE mode allows BAT registers, so re-enable that code.
Change the pegasos PCI_NETBSD_CONFIGURE arguments around to wire up mem
space into the correct area, and move the io regs a little to make it
work properly. Just avoid the secondary PCI entirely.
Change the list of things that we fiddle with in pci_conf_hook. Map mem
on the fwohci, avoid display cards, avoid IO on the auvia.
Change some printf's to aprint_*
Yank a call to genppc_pci_indirect_make_tag and change it to the
bus-independant pci call instead. (in pci_conf_hook)
 1.2  17-Oct-2007  garbled branches: 1.2.2; 1.2.4; 1.2.6; 1.2.8;
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.
 1.1  01-May-2007  garbled branches: 1.1.2; 1.1.6; 1.1.8;
file pchb.c was initially added on branch ppcoea-renovation.
 1.1.8.1  18-Oct-2007  yamt sync with head.
 1.1.6.1  02-Nov-2007  joerg More diff reduce to HEAD due to botched up merging.
 1.1.2.3  21-May-2007  nisimura Fix a mis-placed closing brace to match PCI_PRODUCT().
 1.1.2.2  02-May-2007  macallan make this compile without PREP_BUS_SPACE_IO
 1.1.2.1  01-May-2007  garbled Create a few generic functions and drivers for powerpc.
First, we have a generic pci_machdep.c, which is incomplete, but contains
a number of functions that are generally present in all powerpc
pci_machdep.c implementations.
Second, we have a generic implementation of indirect configuration space
read/write.
Lastly, a generic pchb driver for most of the ppc ports.
