Major cleanup of alpha device drivers.
Switch to CFATTACH_DECL_NEW.

PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional
role in NetBSD (drivers are no longer supposed to write these to
pa_flags) without changing name. Correct that.

Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and
PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names
consistent with the other PCI flags and poisoning 3rd-party driver
sources that use the flags in the old bad way.

This patch produces no binary changes in this set of PCI kernels when
they are compiled w/o 'options DIAGNOSTIC' and w/ -V MKREPRO=yes:

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.

Add MI todr(9) support and timercounter(9) support with kern_cctr.c to alpha:
- use todr(9) API with MI mc146818(4) driver and remove homegrown
todr stuff from MD alpha/clock.c and alpha/mcclock.c
- also remove obsolete cc_microtime stuff from MD code
- add ci_pcc_freq member in struct cpu_info for cpu_frequency(), and
calibrate it with mc146818 interval clock in mcclock attachment
- call cc_init() in cpu_initclocks(9) because all alpha cpus have
a pcc counter

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

branches: 1.14.2;
Handle 64bit DMA addresses on PCI for platforms that can (currently only
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

Use aprint_normal() for cfprint routines.

Use CFATTACH_DECL().

Declare all cfattach structures const.

* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

Remove unnecessary #include <sys/malloc.h>

Don't use a bunch of switch() statements in the core logic drivers to select
the PCI interrupt initialization routine. Instead, register said routines
by systype in a link set, and look them up and invoke them in a new function
alpha_pci_intr_init().

Sprinkle some static.

branches: 1.55.2;
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?).

New platforms: Mikasa and Mikasa/Pinnacle, aka Pinkasa.

Like the 1000A, the AlphaServer 1000 has a daughtercard assembly that
integrates the CPU and core logic, so these can be ev4/apecs or ev5/cia.
New systype, and, sigh, another way of doing interrupts and another
mystery icu.

Kill off some EVCNT_COUNTERS calls, since [A] it has to be rewritten anyway
before it can be useful, and [B] #ifdefs do not belong at every call site,
a common API should be defined and the implementations conditionalized, not
all the calls. Duhh.

Call pci_1000a_pickintr() like on other platforms, but for 1000a expand
the iot, memt, and pc in the call so that pci_1000a_pickintr() (and the
other routines in that module) do not need to be aware of the core logic
type just to pass down memory and I/O space tags or to call the decompose
function.

Don't call *_dma_init() twice; there's no need to. Just do it in *attach().

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

clean up copyrights and RCS IDs

update for new ISA/EISA/PCI and 'bus' interfaces.

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

to parents with different autoconfiguration semantics.

wholesale update from my NetBSD/Alpha source tree. Includes:
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.

Add support for chaining DMA windows together, for falling back on
SGMAPs if a direct-mapped window fails.

Simplify the direct-mapped DMA case somewhat by adding a window base

base as an additional argument.

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?).

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

Split up using BWX for PCI config and bus access. Default to using BWX for
the former, but not the latter. Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access. (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

New platforms: Mikasa and Mikasa/Pinnacle, aka Pinkasa.

mystery icu.

Kill off some EVCNT_COUNTERS calls, since [A] it has to be rewritten anyway
before it can be useful, and [B] #ifdefs do not belong at every call site,
a common API should be defined and the implementations conditionalized, not
all the calls. Duhh.

Call pci_1000a_pickintr() like on other platforms, but for 1000a expand
the iot, memt, and pc in the call so that pci_1000a_pickintr() (and the
other routines in that module) do not need to be aware of the core logic
type just to pass down memory and I/O space tags or to call the decompose
function.

also enables BWX. Make sure it's enabled if we have an old, buggy firmware
rev.

Add support for using BWX for PCI config space and PCI i/o and mem space
on the ALCOR2 and Pyxis. BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.

Ok, now we _REALLY_ have Pyxis recognition correct. There are two systypes
that can have Pyxis: EB164 (AlphaPC164LX and AlphaPC164SX) and DEC_550 (Miata),
and these systypes/variations _always_ have Pyxis.

Garbage-collect the old confargs stuff that was used in the Early Days.
It isn't really appropriate anymore. Replace it with a real mainbus
attach args structure.

Use flags instead of a bunch of booleans. Add a "use bwx" flag.

Rework ALCOR/ALCOR2/Pyxis recognition Yet Again. (Actually, just the
way it's displayed, and mask off the revision once we've determined
which chip we're talking to.)

Try (again) to get the chip number right for Alcor and Pyxis, using the
following (iffy) hueristic:

CIA revision 1 -> 21171
CIA revision 2 -> 21172
CIA revision > 2 -> 21174

We can't count on the CIA revision register telling us if we're a 21171
or 21172, so make the chip/revsion output a little more sane.

Don't assume that we'll be using direct-mapped DMA for PCI.

Adjust for config changes.

Clean up printing of chipset revision/capabilities.

of this code has been tested. (Checkpoint of work in progress.)

single bus_space_* framework. Unfortunately, bus_space_{read,write}_*
operations still imply barriers. That will change soon.

backout previous kprintf change

For CIA/Pyxis and Tsunami/Typhoon/Titan, save the firmware's idea of
the DMA window configuration, and restore it at shutdown time. Make
sure that all assumptions we've made on the firmware's configuration
of DMA windows is correct.

Oops, pass the correct bus_dma_tag_t to the "hi" sgmap init function.

Back in rev 1.21, mhitch@ fixed an issue with his 1.5GB RAM PWS 500au
by using a fall-back to the ISA DMA window if DMA was out of range for
the 1G @ 1G PCI DMA window. Alas, the ISA DMA window is pretty small
(8M @ 8M), and it's possible to starve it with PCI devices that might
have, for example, large control data structures there.

So, instead, if the system has more than 1G of RAM, use Window 3
(previously unused) as a SGMAP window 1G @ 3G, and set that as the
fall-back if the direct-mapped window fails.

Duuuh! Align the SGMAP page tables to 32K, not 32M.

Don't call *_dma_init() twice; there's no need to. Just do it in *attach().

Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically,
the scatter/gather TLB cannot be invalidated on these chips. So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.

Allow the DMA tag to specify a boundary contraint. If the device has a
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

Add support for chaining DMA windows together, for falling back on
SGMAPs if a direct-mapped window fails.

Simplify the direct-mapped DMA case somewhat by adding a window base
member to the DMA tag, and calling the direct-mapped back-ends directly,
rather than through chipset-specific front-ends which pass the window
base as an additional argument.

Use the common _bus_dmamap_sync() as the _dmamap_sync method in the
bus_dma_tag_t.

Put SGMAP-related stuff in the DMA map structure directly, rather than
indirecting through a pointer.

Fix initialization of DMA window 0:
- Make sure the page table is aligned to at least 32k.
- Don't consider the MEMCS signal when checking for a window hit.

Apparently, new AlphaStation 500/600 firmware has the same problem with

it after accessing configuration space), not just eb164's.

This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either. Thanks to Matt Jacob for pointing out this goof.

branches: 1.1.4;
wholesale update from my NetBSD/Alpha source tree. Includes:
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.

Convert the Alpha port's bus_space back-end to manage address space
with vmem(9) arenas (using statically-allocated private boundary tags
for very early-in-boot) rather than extent(9).

As a side-effect, there's arguments to some initialization functions
that are no longer required, so garbage-collect those, update all the
call sites.

For CIA/Pyxis and Tsunami/Typhoon/Titan, save the firmware's idea of
the DMA window configuration, and restore it at shutdown time. Make
sure that all assumptions we've made on the firmware's configuration
of DMA windows is correct.

Back in rev 1.21, mhitch@ fixed an issue with his 1.5GB RAM PWS 500au
by using a fall-back to the ISA DMA window if DMA was out of range for
the 1G @ 1G PCI DMA window. Alas, the ISA DMA window is pretty small
(8M @ 8M), and it's possible to starve it with PCI devices that might
have, for example, large control data structures there.

So, instead, if the system has more than 1G of RAM, use Window 3
(previously unused) as a SGMAP window 1G @ 3G, and set that as the
fall-back if the direct-mapped window fails.

Split up using BWX for PCI config and bus access. Default to using BWX for
the former, but not the latter. Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access. (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

Add support for using BWX for PCI config space and PCI i/o and mem space
on the ALCOR2 and Pyxis. BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.

Use flags instead of a bunch of booleans. Add a "use bwx" flag.

Rework ALCOR/ALCOR2/Pyxis recognition Yet Again. (Actually, just the
way it's displayed, and mask off the revision once we've determined
which chip we're talking to.)

If the CIA revision is >= 2, read the CIA configuration register, and
remember its contents. Print out a bit of information about the chip,
including whether or not it supports the EV56 BWX instructions.

cia_bus_ -> cia_swiz_bus_

Treat bus space tags more like pci chipset tags and bus dma tags: allocate
them statically within a chipset's state structure, and pass them to
the *_bus_{io,mem}_init() functions.

update for new extent management code

update for new bus.h macros. bus_io_* and bus_mem_* integrated into
single bus_space_* framework. Unfortunately, bus_space_{read,write}_*
operations still imply barriers. That will change soon.

store HAE_MEM and HAE_IO register contents in the cia configuration

branches: 1.42.2;
Don't use a bunch of switch() statements in the core logic drivers to select
the PCI interrupt initialization routine. Instead, register said routines
by systype in a link set, and look them up and invoke them in a new function
alpha_pci_intr_init().

Remove the "first" argument from pci_kn8ae_pickintr(), instead using
a real once control in that function. Removes a needless divergence from
other "pickintr" routines.

branches: 1.40.2;
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: 1.39.4;
Changes to make interrupt {,dis}establish MP-safe on Alpha:
- Protect all of the system interrupt linkage with the cpu_lock mutex.
- Re-order some of the stores to the SCB vector table to make it safe
in the face of lockless interrupt dispatch.
- Add a framework for routing interrupts to specific CPUs. Interrupts
are still funneled only to the primary CPU, but that will change for
some systems soon. Ensure that interrupt handler lists are manipulated
only on the CPUs that handle that specific interrupt source. This required
a re-factor of the alpha_shared_intr_*() family of functions.
- Enable __HAVE_INTR_CONTROL, although interrupt redistribution is still
a no-op.
- Reduce code duplication in the Jenson direct-SCB interrupt handlers.

Do a minor cleanup of alpha (this will make applying pullups post branching
easier).

PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional
role in NetBSD (drivers are no longer supposed to write these to
pa_flags) without changing name. Correct that.

Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and
PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names
consistent with the other PCI flags and poisoning 3rd-party driver
sources that use the flags in the old bad way.

This patch produces no binary changes in this set of PCI kernels when
they are compiled w/o 'options DIAGNOSTIC' and w/ -V MKREPRO=yes:
