Fixed issues noted by Christoph Hellwig, and I changed device table
scan a bit to allow the case that some models of graphics chips may
have same host bridge type. This type of chip will be added in the future.
This patch cleans up device probe function. Eric Anholt was the original author.

After SRST, libata used to wait for nsect/lbal to be set to 1/1 for
the slave device. However, some ATAPI devices don't set nsect/lbal
after SRST and the wait itself isn't too useful as we're gonna wait
for !BSY right after that anyway.
Before reset-seq update, nsect/lbal wait failure used to be ignored
and caused 30sec delay during detection. After reset-seq, all
timeouts are considered error conditions making libata fail to detect
such ATAPI devices.
This patch limits nsect/lbal wait to around 100ms. This should give
acceptable behavior to such ATAPI devices while not disturbing the
heavily used code path too much.

The ata IRQ ack functions are only used when debugging. Unfortunately
almost every controller that calls them can cause crashes in some
configurations as there are missing checks for bmdma presence.
In addition ata_port_start insists of installing DMA buffers and pad
buffers for controllers regardless. The SFF controllers actually need to
make that decision dynamically at controller setup time and all need the
same helper - so we add ata_sff_port_start. Future patches will switch
the SFF drivers to use this.

Most drivers don't seem to fill out the host->irq field, resulting in the
wrong (no) irq being reported at probe time. For example, sil24 on my system:
ata1: SATA max UDMA/100 cmd 0xd00008009001f000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0
ata2: SATA max UDMA/100 cmd 0xd000080090021000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0
Since they're allocated and set up in ata_host_activate(), just save
them away there.

This patch moves flexcop-dma (currently used only by flexcop-pci) to
b2c2-flexcop-pci module, that is dependent on CONFIG_PCI, fixing the bug
as reported by Geert Uytterhoeven <geert@linux-m68k.org>:
drivers/media/dvb/b2c2/flexcop-dma.c uses the PCI DMA API, but
DVB_B2C2_FLEXCOP doesn't depend on PCI, causing the following problem on
PCI-less systems:
| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'
| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'
Apparently this is the flexcop DMA core, which is used by both
DVB_B2C2_FLEXCOP_PCI and DVB_B2C2_FLEXCOP_USB.

workhandler
Sliced VBI transfers use PIO instead of DMA. This was done inside the
interrupt handler, but since PIO accesses are very slow this meant that
a lot of time was spent inside the interrupt handler. All PIO copies are
now moved to a workqueue. This should fix various issues with missing time
ticks and remote key hits.

If the SAA7111 device is powered down, and requires re-initialisation when
the V4L device is opened (as on the NetWinder), the SAA7111 driver gets
completely confused about the current settings.
The problem is centred around the way the driver keeps _two_ cached copies
of the current settings - one of the struct video_picture settings, and one
of the registers.
When the decoder is re-initailised, the cached register settings are
overwritten, as are the values in the hardware registers. However, the
cached video_picture settings are not.
Resolve this by removing the useless and buggy second level of caching for
video_picture. Instead, provide a function which updates register values
if and only if the value we are going to write to the register has changed.

Currently when system which have HPA require HPA to be detected and
disabled upon resume from RAM or disk. The current IDE drivers do not do
this nor does libata (obviously it since it doesn't support HPA yet).
I have implemented this into the current IDE drivers and it has been
tested by many others since 7/15/2006 in bug number 6840:
http://bugzilla.kernel.org/show_bug.cgi?id=6840
and it has been confirmed to work fine with no problems.

The DMA support for RAID mode broke after:

  [PATCH] ide: if the id fields looks screwy, disable DMA
  It's the safer choice. Originally due to a bug in itx821x, but a
  generally sound thing to do.
  Signed-off-by: Jens Axboe <axboe@suse.de>
However it worked by pure luck before Jens' fixes: bogus ide_dma_enable()
usage in it821x driver combined with loosy check in ide_dma_verbose() allowed
the hardware to operate in DMA mode. When these problems were fixed the DMA
support broke...
The source root for the regression turned out to be that the it821x.c code
was clearing too much of id->field_valid. The IDE core code was using the
original value of id->field_valid to do the tuning but later DMA got disabled
in ide_dma_verbose() because of the incorrect id->field_valid fixup. Fix it.
While at it:
* Do fixup() after probing the drives but before tuning them (which is also
OK w.r.t. ide_undecoded_slave() fixup). This change fixes device IDENTIFY
data to be consistent before/after the tuning and allows us to remove extra
re-tuning of drives from it821x_fixups().
* Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has
DMA capable bit set (this is just to tell the IDE core that DMA is
supported since it821x firmware takes care of DMA mode programming).
* Don't touch timing registers and don't program transfer modes on devices
et all when in RAID mode - depend solely on firmware to do the tuning
(as suggested by Alan Cox and done in libata pata_it821x driver).
Thanks for testing the patch goes out to Thomas Kuther.

Problem noticed by Joe Zbiciak, see
http://kerneltrap.org/node/8252
for details.
On CSB6 the driver is using BIOS settings and not programming DMA/PIO timings
itself. However the logic was completely broken and resulted in wrong timings
being silently allowed (instead of being corrected by the driver).
This bug would explain some data corruption/timeout issues with Serverworks
MegaIDE in RAID mode that Alan Cox has fixed recently with:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2074a106f52b6371885afbd714e929d60d0e3f64
For 2.6.23 we may be better off with completely switching the driver to always
programming timings (libata pata_serverworks.c driver is doing things this way
and there were no problems reported so far) but for 2.6.22 lets fix the bug
in the simplest and the least intrusive way.

With firmware 5.220.11.p5, this allows to specify the anycast addresses the
device will listen to.
The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or
0 to 31 in dec). The value to write on anycast_mask will specify which
addresses the device listens to. Bits in a 32 bit int are numbered from 0
(least significative bit) to 31. A specific address ending in YY will be
listened to if bit YY in the value is set to one.
Examples:
0x00000000 : do not listen to any anycast address
0xFFFFFFFF : listen to every anycast address from :00 to :1F
0x00000013 : listen to anycast addresses :00, :01 and :04
