Remove unnecessary <sys/malloc.h>.

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?).

use the generated macros in locators.h rather than hard-coded numbers
to index the cf_loc[] array. reviewed by allen briggs.

Always use `full bus space'. In order to implement this more efficiently,
require that all bus tags have pointers to bus_space_read/write functions,
i.e. no run-time hunting for the first "upstream" implementation.
Since this changes the way bus tags should be constructed it makes sense
to do the same thing for the rest of the bus space methods.
So, now bus space tags are generally constructed by copying the parent's bus
tag and then overriding the methods that the bus driver needs to handle,
instead of starting with an empty bus tag and fiiling in only the fields needed.

Use aprint_normal() for cfprint routines.

Use CFATTACH_DECL().

Declare all cfattach structures const.

Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.

Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver. The cfdriver is then looked
up in a list which is built at run-time.

Put a bus's ranges in the bus space tag, and make sparc_bus_map()
perform the translation and recursion if t->ranges != NULL. Make
sbus, cpuunit, and bootbus inherit the parent's map/mmap routines,
and delete the now-unused mapping functions. Update all places where
bus space tags are statically allocated.

Remove obio_bus_probe().

Only print interesting interrupt levels.

Switch to a bus_space(9)-based device attachment scheme.

- device attachment arguments contain bus-specific
address and interrupt levels.

- devices must call back on bus map functions to get their
addresses and interrupt levels translated properly.

- sun4m's obio bus is treated like an Sbus slot.

- the sun4-style obio bus has its own attach arguments
and map functions.

All VME stuff is gone from here.

Update for changes to config.

%x -> 0x%x

vme_establishintr: remove SUN4 arch check; this now works on sun4m as well.

Use the `ranges' property to deal with VMEbus address spaces.

Use `rr_iospace' to track the MMU page type bits. On sun4c/sun4m the
iospace value is always learned from the PROM; on sun4, we infer it
from the BUS_* parameters.

This obsoletes the `bustype' argument in bus_tmp().

Remove bus_tmp(); it's just a special case of mapdev().

A bit of framework for sun4m VME busses.

Move "range" property description out of generic `romaux'.
Allocate room for this property when needed in bus attachment.

backout previous kprintf change

printf -> kprintf, sprintf -> ksprintf

change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

don't set tmp twice.

make netbsd/sparc boot on sun4 once again. the sun4m changes introduced
config lines for obio0 devices without addresses (thus cf->cf_loc[0] took
the default value of -1). we now ignore these entries on a sun4 since
they could never be valid (eliminates a 'panic:alignment' fault at bootup).

Handle sun4m `obio' devices.
Cleanup `#if defined(SUN4*)' mess.

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Bring prototypes into scope and fix compiler warnings.

improved handling of mapping of devices who's registers do not reside on
page boundaries:
- change bus_tmp() to include the offset from the start of page in the
returned KVA [rather than forcing each driver to add it back in
individually]
- changed bus_map() to include the offset from the start of page in the
the returned value if a mapping is found in the PROM's KVA area
- clarified a few comments

Correct page frame calculation after mapdev() interface change.

Adapt to changed mapiodev() interface.

Use actual bus names (matches Chuck's bootpath code).
