Add support for the Promise PDC4071[89] chips used on fx the Fasttrak TX4300.
Docs kindly provided by Promise.

Add support for the ITE IT8211F controller.

Add support for the Intel 31244.
Most code by the submitters, hammered upon to get the right ATA fell by me.

Change the way ioctls are issue to ATA.
The most prominent part is that its now possible to issue ata_requests
directly to say acd0, instead of going through the cumbersome /dev/ata
device.

Cleanup comments

Add new Intel PCI ID's for the ICH7 chips (untested).

Take newbusification one step further, ie use the device_t more consequently
all way through the code down the layers, instead of the mix'n'match that
resulted from the conversion done earlier.

Add one more Promise SATAII/150 chip id.

Refine the SATA PHY code so the time consumed during probe is reduced.

Add the older nVidia nForce2 SATA chip to supported HW.

Add support for the PHY on nVidia, SiS and VIA chips
This code is done blindfolded as I dont have such HW here, so reports
of success/failure are most welcome.

More SATA PHY cleanups.

Generalise the SATA PHY handling code so it wont be duplicated for
each SATA chip.
Promise and Silicon Image are the current candidates for this.

Add firstshot support for Acer Labs Inc SATA parts
Update ALi PATA support to handle ATA133 as well

Correct the PCI ID for the SiS 965, and add support for the SATA part
that was left our by accident.

This is the much rumoured ATA mkIII update that I've been working on.

o ATA is now fully newbus'd and split into modules.
This means that on a modern system you just load "atapci and ata"
to get the base support, and then one or more of the device
subdrivers "atadisk atapicd atapifd atapist ataraid".
All can be loaded/unloaded anytime, but for obvious reasons you
dont want to unload atadisk when you have mounted filesystems.

o The device identify part of the probe has been rewritten to fix
the problems with odd devices the old had, and to try to remove
so of the long delays some HW could provoke. Also probing is done
without the need for interrupts, making earlier probing possible.

o SATA devices can be hot inserted/removed and devices will be created/
removed in /dev accordingly.
NOTE: only supported on controllers that has this feature:
Promise and Silicon Image for now.
On other controllers the usual atacontrol detach/attach dance is
still needed.

o Support for "atomic" composite ATA requests used for RAID.

o ATA RAID support has been rewritten and and now supports these
metadata formats:
"Adaptec HostRAID"
"Highpoint V2 RocketRAID"
"Highpoint V3 RocketRAID"
"Intel MatrixRAID"
"Integrated Technology Express"
"LSILogic V2 MegaRAID"
"LSILogic V3 MegaRAID"
"Promise FastTrak"
"Silicon Image Medley"
"FreeBSD PseudoRAID"

o Update the ioctl API to match new RAID levels etc.

o Update atacontrol to know about the new RAID levels etc
NOTE: you need to recompile atacontrol with the new sys/ata.h,
make world will take care of that.
NOTE2: that rebuild is done differently from the old system as
the rebuild is now done piggybacked on read requests to the
array, so atacontrol simply starts a background "dd" to rebuild
the array.

o The reinit code has been worked over to be much more robust.

o The timeout code has been overhauled for races.

o Support of new chipsets.

o Lots of fixes for bugs found while doing the modulerization and
reviewing the old code.

Missing or changed features from current ATA:

o atapi-cd no longer has support for ATAPI changers. Todays its
much cheaper and alot faster to copy those CD images to disk
and serve them from there. Besides they dont seem to be made
anymore, maybe for that exact reason.

o ATA RAID can only read metadata from all the above metadata formats,
not write all of them (Promise and Highpoint V2 so far). This means
that arrays can be picked up from the BIOS, but they cannot be
created from FreeBSD. There is more to it than just the missing
write metadata support, those formats are not unique to a given
controller like Promise and Highpoint formats, instead they exist
for several types, and even worse, some controllers can have
different formats and its impossible to tell which one.
The outcome is that we cannot reliably create the metadata of those
formats and be sure the controller BIOS will understand it.
However write support is needed to update/fail/rebuild the arrays
properly so it sits fairly high on the TODO list.

o So far atapicam is not supported with these changes. When/if this
will change is up to the maintainer of atapi-cam so go there for
questions.

Add support for the Promise command sequencer present on all modern Promise
controllers (PDC203** PDC206**).

This also adds preliminary support for the Promise SX4/SX4000 but *only*
as a "normal" Promise ATA controller (ATA RAID's are supported though
but only RAID0, RAID1 and RAID0+1).

This cuts off yet another 5-8% of the command overhead on promise controllers,
making them the fastest we have ever had support for.

Work is now continuing to add support for this in ATA RAID, to accellerate
ATA RAID quite a bit on these controllers, and especially the SX4/SX4000
series as they have quite a few tricks in there..

This commit also adds a few fixes to the SATA code needed for proper support.
