Remove unnecessary <sys/malloc.h>.

Merge thorpej-cfargs2.

Adapt to CFARGS().

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?).

Convert config_found_ia() call sites where the device only carries
a single interface attribute to bare config_found() calls.

Style and cosmetic changes. No binary changes intended.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged

this commit was splitted into small chunks to avoid

Support Synopsys DesigneWave OTG on PowerPC 405EX.

Catchup with rmind-uvmplock merge.

Use <sys/foo.h> instead of <machine/foo.h> if such a file exists.
Don't assume <sys/cpu.h> includes <powerpc/subarch/cpu*.h>.  Include it
explicitly.

Fix PR#43911.

Whitespace.

Add IBM405GPr "External Bus" driver.

Implement 405GPr's "External Bus" as exb(4).

Sync with HEAD.

Support PowerPC 405EX/EXr.
  1. Add some new source and header files.
     (MAL(split) and RGMII(new) relations for EMAC)
  2. Create dcr4xx.h.  Its moved from dcr405gp.h.  Also remove dcr405xx.h.
  3. intr.c supports MULTIUIC with virtual-irq.  likes to oea.
     support 32-virq/128-hwirq.
  4. multiple emac support.
  5. WALNUT and VIRTEX_* includes arch/powerpc/conf/files.ibm4xx.
  6. WALNUT pci uses arch/powerpc/ibm4xx/pci/.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

convert remaining autoconf bus "submatch" functions to use the new
signature (passing locators), and remove some which obviously don't
serve any purpose
(untested, sorry)

Fix the sync with head I botched.

Sync with HEAD.

Uppercase CPU, plural is CPUs.

Fix the default bus dma tag.

Switch ibm4xx over to using the more flexible powerpc bus_space/bus_dma code.

__KERNEL_RCSID()

Sync with HEAD.

Use aprint_normal() for cfprint routines.

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Add trailing ; to CFATTACH_DECL.

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.

sync kqueue branch with HEAD

file plb.c was added on branch kqueue on 2002-09-06 08:39:10 +0000

file plb.c was added on branch gehenna-devsw on 2002-08-31 13:45:45 +0000

Add "ecc at plb" device.
Add an "irq" locator to the plb device.
This gets rid of the original hack where ecc support was wedged into
the cpu driver.

Use "ibm4xx" instead of "galaxy"; galaxy was an early code name for the
405GP.

Catch up to -current.

Reorganise the IBM 4xx bus layout, using terminology from the IBM
documentation:
 - Remove "mainbus" altogether.
 - The new root is "plb" - the Processor Local Bus.
 - Attached to this is the "opb" - the On-chip Peripheral Bus, to which
   all the on-chip devices are attached (except the cpu and pci host
   bridge).
 - Port-specific code can pass an array of 'struct plb_dev' to
   config_rootfound() to attach extra devices to the plb.  The walnut
   port attaches a "pbus" (Peripheral Bus) in here for the RTC and
   pc keyboard controller to attach to.
There is still much 405GP specific code; the next round of changes will
generalise this to enable easier support for other 4xx CPUs.
