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?).

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.

- map 0xc0000000-0xffffffff PA region (which is mirror of PA 0x0-0x3fffffff)
to the same VA via %tt0 and %tt1 registers and move KVA space accordingly
(like luna68k does for its devices)
- save trap #0 vector for PROM function calls in early bootstrap
and register it to trap #14 to call it from kernel for console output
- add dumb romcall based tty attachment taken from src/sys/dev/ofw/ofcons.c
- add rom function call stubs from news68k/stand/common/romcalls.S
- remove IIOV() macro for device registers where now mapped PA==VA via %tt1

XXX: romcons is not enabled yet because there is no generic interface
XXX: to attach wskbd(4) to non wsdisplay(4) devices like this romcons.

branches: 1.6.2; 1.6.8;
Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

Fix few more typos along the way, mainly in copy-pasted comments.

Merge thorpej-cfargs2.

branches: 1.32.8;
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?).

branches: 1.31.64;
Add preliminary PROM internal function based framebuffer console support,
which was demonstrated at Open Source Conference 2011 Kansai @ Kyoto
back in July:
http://www.NetBSD.org/gallery/events.html#opensourceconf2011-Kansai

to the same VA via %tt0 and %tt1 registers and move KVA space accordingly
(like luna68k does for its devices)

Remove clause 3 and 4 from TNF licenses

branches: 1.29.2; 1.29.4;
Split softc and device_t for zsc(4) and its children.

XXX we should restructure MI APIs and make it really machine independent.

branches: 1.28.14;
Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

Call zs_lock_init() to set up the chanstate's lock.

branches: 1.26.2;
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.

branches: 1.25.8; 1.25.10; 1.25.14;

LOCKDEBUG kernel fails during console zstty attachment.

branches: 1.24.6; 1.24.8; 1.24.14;

merge ktrace-lwp.

branches: 1.21.2;
- add const
- u_char -> uint8_t

- idrom is stored in ROM, so make it const rather than volatile

- Use ANSI function declarations and make some functions static.
- Some KNF

Include ioconf.h to declare struct cfdriver.

__KERNEL_RCSID()

branches: 1.17.2;
Initialize struct consdev more properly.

KNF

Backout previous. <sys/lock.h> is pulled from <sys/tty.h>.

MI z8530sc driver now requires <sys/lock.h>.

Provide locking required by the interrupt handlers running at IPL_SERIAL.

Fix -Wsign-compare warnings.

Use aprint_normal() for cfprint routines.

Remove __P().

Use CFATTACH_DECL().

Declare all cfattach structures const.

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.

branches: 1.6.2; 1.6.8; 1.6.16;
bcopy() -> memcpy() (I guess there is no overlap here)

branches: 1.5.2;
- Initialize zs chip in zscninit() so that kernel can use
serial console even if the PROM uses bitmap console.
- Remove zs_hwflags since news68k does not have keyboard nor mouse at zs;
check zschan address set in zscninit() to detect console device.
- Use BPS_TO_TCONST() to set baudrate in zs_init_reg[].
- Remove zs_get_chan_addr(), which is not needed anymore.

branches: 1.4.4;
- Implement cnbell() -- ring the console bell. The cn_bell entrypoint
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

Add news1200 support.
Based on a patch from Koichi NISHIWAKI <k-nis@ba2.so-net.ne.jp>

Modify software interrupt handling a bit.

branches: 1.1.2;
