disable MSI for SiI3124 - interrupts don't seem to work on this old board
when MSI is enabled, maybe because it's behind a PCI bridge

PR kern/55115 by John D. Baker

branches: 1.20.4; 1.20.16;
release intr if pci_intr_establish_xname() fails

detach the controller itself on shutdown; adjust to not detach already
detached atabus/channel

first disestablish interrupt, then release

enable MSI support where available, blatantly copied from jmcneill's msk(4)

branches: 1.16.4; 1.16.6;
switch to pci_intr_establish_xname()

match Adaptec 1220SA; that card actually uses Silicon Image 3132, and works
well with the siisata(4) driver

branches: 1.14.6; 1.14.10;
KNF. No functional change.

branches: 1.13.6;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.

Revert previous; the SiI3114 is not even BAR/register compatible with
siisata(4).

branches: 1.11.2;
Recognize 3114.

branches: 1.10.6;
Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive}
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.

branches: 1.9.8; 1.9.12;
Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants. These are provided by sys/param.h now.

branches: 1.8.2;
A pointer typedef entails trading too much flexibility to declare const
and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.

branches: 1.7.2;
Sprinkle __KERNEL_RCSID() into siisata(4).
Slightly adjust some comment styling.

Expand PMF_FN_* macros.

Remove closes 3 & 4 from my licence. Lots of thanks to Soren Jacobsen
for the booring work !

Remove unused elements from siisata_softc.

Clean up siisata pci attachment.
noteable changes:
- Use aprint_*_dev where appropriate.
- Condense board match table and use C99 initializers.
- Use aprint_verbose for extra info.

Also, add 2009 to my copyright, as well as remove my local CVS tags.

A few changes for siisata(4):

- Support detachment. From KIYOHARA Takashi.
- Add PCI detachment functionality (albeit not very interesting when
the bus can not yet be rescanned).
- Rework interrupt handlers to reduce near-duplicate code.
Borrowed from ahcisata(4).
- Attempt to make polled I/O work. Untested.
- Fix formatting of some messages.
- For always-polled commands, disable interrupt
at slot level rather than port level.
- Instead of busy-waiting indefinitely for completion of some commands
move on after 31 seconds. Use cv_timedwait(9) instead of DELAY(9).
- Use abstracted SATA FIS code.
- Enable use of disks that don't respond with the standard signature.

branches: 1.2.2; 1.2.4;
In case the PCI command bits aren't already set, do so before performing
an access that requires them to be. From KIYOHARA Takashi.

Import siisata(4) by Jonathan A. Kollasch.

The siisata driver supports the Silicon Image SteelVine family of SATA-II
controllers, interfacing the hardware with the ata(4) and atapi(4) sub-
systems.

The following controllers are supported by the siisata driver:

Silicon Image SiI3124 4-port PCI/PCI-X
Silicon Image SiI3132 2-port PCI-Express x1
Silicon Image SiI3531 1-port PCI-Express x1

SATA Native Command Queueing is not yet supported.
Device hot swapping is not yet supported.
Silicon Image's Software RAID is not yet supported by the
ataraid(4) driver.
