sparc64: fix interrupt level mapping for disk and and parallel devices
on SBUS-based machines

Change the mapping from PIL_SCSI to PIL_BIO, so that they interrupt above
the highest soft interrupt (softserial)

Remove unused PIL_SCSI, PIL_FDSOFT, PIL_AUSOFT and fix the printf in fdc.c

Add "socal" and "SUNW,bpp" to the interrupt map.

Add "socal" and "SUNW,bpp" to the interrupt map.

Change the devhandle_from_*() functions to also take a "super handle",
from which the newly created handle will inherit it's implementation.
The root implementation for a new handle type is used if an invalid
"super handle" is passed.

- Move all of the stuff-missing-from-OFW-device-tree stuff into a
  new function sparc64_device_tree_fixup(), and call it from
  device_register().
- sparc64_device_tree_fixup() is table-driven, selecting the table
  based on the machine_model.  It can appy "dtnode" fixups (by matching
  the device's OFW path) and "special" fixups, which are especially
  useful when a property needs to be added to another device that happens
  to not be in the OFW device tree.
- Implement enumeration of missing-from-OFW-device-tree i2c devices
  by "sub-classing" the controller's device handle, intercepting the
  "i2c-enumerate-devices" device call.  We let the "super" first
  enumerate any i2c devices that are in the OFW device tree, and then
  enumerate our own additions after that is done.  i2c additions are
  provided by the machine_model fixup tables.

- Define a device call for PCI bus instances to fetch a direct child's
  device handle given the device's device/function #s (extracted from
  a pcitag_t).  Use it to associate the handle with the child device
  at config_found() time.
- Implement this device call for ACPI and OpenFirmware.
- Enable the OpenFirmware variant for evbarm FDT, macppc, ofppc, sparc64.
- Obsolete acpi_device_register(); it is no longer needed.
- Obsolete setting the OpenFirmware handle in PCI devices in the
  sparc64 device_register(); it is no longer needed.

All of the OFW-enumerated busses now associate the OFW node with the
device at config_found() time, so we can remove all of the stuff from
device_register() that does it, leaving only the @pci case to fix that
up (similar situation with ACPI on ARM and x86).

Adapt the boot device matching code to use the devhandle from the
device_t rather than the previous mechanism, and add some comments
explaining what's going on and some assertions to validate the
comments.

Collapse the sun4v vdsk boot device detection into the normal "sd"
case because it's almost identical to the normal "sd" case anyhow.

Associate the OpenBoot / OpenFirmware node with attached devices
at config_found() time.

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?).

Give config_found() the same variadic arguments treatment as
config_search().  This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls.  Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.

Add information about GPIO pin assignments and drive bays in the E250 and
v240.  Consolidate common code for v210/v240 and E250.
Modify the GPIO pin names to include a type (currently LED or INDICATOR)
which we can then handle in the driver.

Move E250 and E450 i2c patches from dev/pcfiic_ebus.c to sparc64/ofw_patch.c.
They are now co-located with the other OFW patch routines.
New i2c devices are created for E250/E450 and v210/v240, so create new
functions to avoid duplicate code.

Avoid declaring autoconf_debug twice when building with DEBUG.
Pointed out by palle@ - thanks!

Add a static EDID entry for the Mesostation-999.

Add support for direct configuration of i2c devices

- store the maximum [id]cache size / line size for each cpu

- remove patch_kernel() since it isn't necessary and has been patching
  the wrong thing in general.

- implement USIII versions of blast_icache(), dcache_flush_page() and
  cache_flush_phys().  use the newly recorded cache size/line sizes.

- in winfixsave, flush the D$ with the right size index and ops.  this
  kills one of the wrong tag->inval patches.

- for blast_dcache(), use the newly recorded dcache_size/line_size.

- for blast_icache(), use the newly recorded cache size/line sizes.
  for the USIII verison, disable the I$ while writing to ASI_ICACHE_TAG.


these changes removed several hard coded cache sizes values, some very
wrong kernel patching, and seem to make the current failure modes for
USIII less common, but not gone.

introduce a new patch_kernel() and call it from the end of bootstrap().
use it to patch up TLB flush instructions that don't match for USI/II
and later.  we can also hopefully use this to make GENERIC.MP minimally
expensive on single CPU machines as well.

this is the last piece needed to get GENERIC/GENERIC.MP to boot on the
USIII* machines.

idea and some initial code from openbsd.

Copy the "shared-pins" property over to device_props as well.

Make sure to not provide the global ethernet address for add on
interfaces w/o FCode (the respective driver will know what to do).

Add the mac address as device property "mac-address" to all devices that
look like a network interface.
Also add a boolean "without-seeprom" to all apparently on-board network
interface (which usually have no eeprom of their own on Suns), this
latter can be used to enable driver hacks.

Better support for FC-AL controllers/boot disks:
 - on FC-AL disks, use wwn instead of target index to match a particular drive
 - use the new device_register_post_config() to match "sd" device against
   the bootpath after they have gained their wwn device property
 - supply firmwares notion of port and node wwn for FC controllers
   as device properties (the builtin ones don't see to have a separate nvram)

Refactor device_register code slightly in preparation for further changes.

As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

If output-device contains a video mode specifier ( as in

Be more precise when matching the boot device - with ata disks and
atapibus cdrom drives both using the same "target/lun" space, we could
confuse cdrom@0,0 for disk@0,0. Now match the complete string (we still
don't care how firmware calls a device, just rely on it being consistent).

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.

ofppc still needs a bunch of work, which I will be looking at.

Extract common code from i386, xen, and sparc64, creating
config_handle_wedges() and read_disk_sectors().  On x86, handle_wedges()
is a thin wrapper for config_handle_wedges().  Share opendisk()
across architectures.

Add kernel code in support of specifying a root partition by wedge
name.  E.g., root specifications "wedge:wd0a", "wedge:David's Root
Volume" are possible.  (Patches for config(1) coming soon.)

In support of moving disks between architectures (esp. i386 <->
evbmips), I've written a routine convertdisklabel() that ensures
that the raw partition is at RAW_DISK by following these steps:

        0 If we have read a disklabel that has a RAW_PART with
          p_offset == 0 and p_size != 0, then use that raw partition.

        1 If we have read a disklabel that has both partitions 'c'
          and 'd', and RAW_PART has p_offset != 0 or p_size == 0,
          but the other partition is suitable for a raw partition
          (p_offset == 0, p_size != 0), then swap the two partitions
          and use the new raw partition.

        2 If the architecture's raw partition is 'd', and if there
          is no partition 'd', but there is a partition 'c' that
          is suitable for a raw partition, then copy partition 'c'
          to partition 'd'.

        3 Determine the drive's last sector, using either the
          d_secperunit the drive reported, or by guessing (0x1fffffff).
          If we cannot read the drive's last sector, then fail.

        4 If we have read a disklabel that has no partition slot
          RAW_PART, then create a partition RAW_PART.  Make it span
          the whole drive.

        5 If there are fewer than MAXPARTITIONS partitions,
          then "slide" the unsuitable raw partition RAW_PART, and
          subsequent partitions, into partition slots RAW_PART+1
          and subsequent slots.  Create a raw partition at RAW_PART.
          Make it span the whole drive.

The convertdisklabel() procedure can probably stand to be simplified,
but it ought to deal with all but an extraordinarily broken disklabel,
now.

Rework boot device matching to get rid of lots of special case code
and tables to map fimware names to driver names. Based on a suggestion
from Eduardo (quite some time ago).
Each device (on busses we can handle and care about) gets a device property
storing the devices OpenFirmware package handle. To match the boot device,
the phandle of the chosen bootpath is compared against this property,
plus some additional string matching for disk/cd devices (where OF only
provides a node for the device class, not each instance).

Alter sparc64 bootstrap, catch up to ofwboot v1.9:

 - Change kernel entry address to point directly at the code instead of pointing
   at the trap table's first slot. This allows the bootloader to detect
