dc26948b0c Fix the handling of "inflight" requests when doing reinit's.
Add missing untimeout that would get lost in handling of some
error situations, and caused what looked like random timeouts
afterwards when the timeout fired.

a4c3e742b7 Refine the wait for ATAPI_RESET.
Properly wait for not busy and introduce a timeout for devices not

Leave a printf in there that states how long the wait was, as I'd like
to get an idea of the variations here. The time needed seems also to be
affected by whether a medium is present or not.

3c632a5847 atapicam(4) is currently off by three orders of magnitude regarding the
timeout values in the CAM CCBs.  Divide by 1000 to get values in seconds
which are what ata(4) timeouts internally use.

This does lose granularity, though, and small values can now round down
to zero.  It's probably worth making all ata(4) timeouts in terms of
hz/ticks/milliseconds/something.

f2972d7eb8 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.

0b7ed341e1 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

a7a120f649 Overhaul of the timeout/reinit framework. This should clear up most
of the leftovers from the old version that really doesn't work anymore.

Add a reset function for host-end of the ATA channel. This is needed
for the SiI3112 in order to whack it back to reality if a device
locks up the SATA interface (thereby preventing that we can reset the
device). The result is that ATA now recovers from the timeouts that
happens with the SiI3112A and more or less all disks based on old
PATA electronics with a Marvell PATA->SATA converter. This includes
lots of the popular SATA dongles and the WDC Raptor disks..

Setup decent transfer mode defaults as some BIOS's seem to put in
things that it *knows* doesn't work.
(Note to BIOS writers: stop doing that nonsense, we will get things
working with your crappy HW anyways, and then recommend users to buy
someone else's products that "just works", thankyou.. )

Limit the device transfer mode to ATA100/UDMA5 on generic SATA.
 Since we dont know if the user is using a pure SATA device or an
old PATA drive with a SATA converter dongle, we need to limit the
speed used here to cover up the problems with Marvell ATA-SATA bridges
used in lots of SATA products.

This workaround is enabled for all detectable SATA controllers as they
seem to have semilar problems here. One notable exception is all the
Promise pdc2037x chips which just always work (cudos to Promise!).

12146c454b Fix burning of CD's that got broken by the GEOM'ification.
GEOM was not designed to handle media that does not have
a size. Blank CD's are of that type, so cheat and set the
media size to -1. This allows burning to work, but makes
GEOM issue outofrange reads that makes the ATAPI subsystem
spew out a few warnings. GEOM should be tought about this.

GEOM was not designed to handle changing the sectorsize
between opens. Writing multitack CD's with both audio and
data tracks needs to change sector size on the fly. We
cheat here and stuff the current sectorsize into GEOM
private internals. GEOM should grow some clean way for this.

80344be509 Fix the DMA problem that most severely hit on the DS3112a SATA chip
in connection with Marvell based SATA->PATA dongles.

The problem was caused by a combination of things working
together to make it hard to spot...

The ATA driver has always started the ATA command, then build
the SG list for DMA and then finally started the DMA engine.
While this is according to specs, it poses a potential
problem as some controllers apparently do not allow for unlimitted
time between starting the ATA command and starting the DMA engine.

At about the same time as ATAng was committed there were lots
of other changes applied, some of which was locking in parts
that causes the busdma load functions to take significantly
longer to load the SG list.

This pushed the time spent between starting the ATA command and
starting the DMA engine over the hill for some controllers
(especially the Silicon Image DS3112a) and caused what looked
like lost interrupts.

The solution is to get all the SG list work or rather all
busdma related stuff done before we even try to start anything.

This has the nice side effect of seperating busdma out the
way it should be, so the working of the ATA machinery is not
cluttered up with busdma droppings, making the code easier
to read and understand.
