	sys/dev/pci/mpii.c: revision 1.30

Fixes for PR kern/57133:

I can now explain why this assert is firing and have a fix for it.  It is a  regression introduced in R1.22 of mpii.c.

        If a request comes in and the IOC returns a MPII_SCSIIO_STATUS_CHECK_COND condition, after
 a successful transfer, or one that is a recovered error,
 mpii(4) correctly sets the xs->error to XS_SENSE, but incorrectly sets xs->resid to 0 before
 returning the xfer to the upper scsi layers.  Once the upper layers get it, they notice the
 XS_SENSE check condition and because it's a retryable error, they increment xs_requeuecnt, set
 ERESTART and send the xfer request down to the mpii(4) layer again for a retry. What they do
 not do is reset xs->resid equal to xs->datalen.  When the xfer comes down to mpii(4) again, the
 assert happens.  The fix is for the mpii(4) driver to leave xs->resid alone when it encounters
 a MPII_SCSIIO_STATUS_CHECK_COND condition.

This bug affects NetBSD-10, netbsd-9 and netbsd-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?).

PR/54045

fix mpii to adhere to physio diagnostic invariant that
fully processed data must not post an error:

1) verify expected scspi state via KASSERT() instead of just
    setting the variables.
2) set xs->resid only in known good conditions
3) insure setting errors in all error paths and refrain
    from clearing xs->resid in error paths.

While there do some cosmectic clean up:
1) extend and relocate some debug output
2) mpii HBAs can also manage non-disk devices like tapes etc,
    so log that physical "devices" instead of physical "disks" are
    attached or detached.

Tested with NEOSeries FlexStor II and luckily a broken tape drive 8-(

Update the mpii(4) driver to the latest OpenBSD version.

This adds support for the SAS3xxx LSI controllers, and this also makes the
driver MP-safe.

Add some definitions from OpenBSD, needed by the upcoming mfii driver.
No functionnal change.

 -

Move registers definitions to a separate file, needed for the upcomning mpii
driver. No functionnal change.

 -

Add mpii(4), a driver for LSI Megaraid Fusion controllers.
Ported from OpenBSD. This driver is MP-safe.

Note that the earlier fusion controllers (Megaraid 2208, codenamed Thunderbold)
are also supported by mfi(4). mpii will take precedence if both drivers
are enabled.

symptoms:

         are padded to requested block size with
         a 5a... a5... pattern.
problems fixed:
         - controller scsi_status values did not match

           a mapping function was introduced.
         - when experiencing an underrun (read 64k and

           not a SUCCESS status but CHECK status. handle
           that like SUCCESS adjusting xs->resid and set
