Merge thorpej-cfargs2.

branches: 1.37.8;
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?).

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.

- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.

- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

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).

Modified to get cleaner match/attach code for different parent buses.
Fix so that resource wait queueing works.
Changed all functions to take a pointer to uba_softc instead of unit
number, except for ubareset(). This must be done later.

Automatic changing of root device after boot now works.

Remove code that took care of old config devices. Don't support
old config anymore, all devices should use new config by now.
Add structures to handle DMA devices using new config.
Fixed bug that caused unwanted ubareset's on 11/780.

Added prototypes to everything. Made all files compile with -Wall.

Ubareset are now possible, devices that wants it now set it up
during autoconfig. ifubareset (if_reset) no longer used, actually
it's just a normal ubareset and is now handled like that.

Convert all devices according to the changes to config.

Check on which SBI we are frobbing, not always 0.

Support for VAX 8600/8650 added. Works with lots of Unibus adapters,
and will probably work with Massbus adapters as well. (Not tested,
but it's the same code as for 11/780). Ubareset's may cause crashes
on 8600 also like 11/780, but they are more uncommon. No support
for console RL02 yet, but it's likely to come.

Add support for DW780. Note that ubareset's don't work properly.
This is not a problem on other Unibus adapters, but DW780's do
ubareset's more often. This needs to be fixed by someone someday.

Remove csralloc(), not usable anymore.
Add ubasetvec() to steal interrupt vectors for device drivers that
need more than one vector. Add prototype for it.

vax/uba: fix detection of CMD CQD-22x MSCP controllers

Certain models of CMD MSCP controllers fail to be detected by uda(4) if
they have been booted from. This failure mode has been introduced in
revision 1.11 of uba_mainbus.c, when scanning for Qbus/Unibus memories
was added. They are deteced fine when NetBSD is booted from any other
device such as over the network.

When NetBSD is booted from a MSCP controller, the boot loader sets up
the Qbus map to provide the controller with a small command/response
ring in memory to be used for I/O. Once the kernel is loaded and uba(4)
is attaching, the Qbus map is cleared while scanning for memories. It
appears that sudden loss of access to the command/response ring causes
the firmware of these CMD controllers to drop dead.

As a result, these controllers don't react in a reasonable time (100ms
by the spec) when their IP register is written to re-initialze the
controller. Even though uda(4)'s udamatch() waits up to 10s for a sign
of life from the controller, that's usually not enough for it to wake
up and it is assumed to be absent. Which, of course, causes the kernel
to fail booting as the boot device can't be found.

This needs to be addressed both in the kernel and the bootloader.

We can work around this issue in the kernel by restoring the Qbus map
registers to their original values after we've used them for detecting
Qbus memories. The code to do that is already there but commented out,
it just needs uncommenting.
