Additionaly to being bloat the code contained two bugs:
- wrong cable bit was checked (0x0001 instead of 0x8000) on ATA_133 chipsets
- incorrect UDMA cycle time was reported on ATA_100a/ATA_133 chipsets

9ff6f72f43 ide: remove hwif->autodma and drive->autodma
* hpt34x.c: disable DMA masks for HPT345
  (hwif->autodma is zero so DMA won't be enabled anyway).

* trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag
  (hwif->autodma is zero so DMA won't be enabled anyway).

* Check noautodma global variable instead of drive->autodma in ide_tune_dma().

  This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris,
  au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers.

* Remove hwif->autodma (it was not checked by IDE core code anyway) and
  drive->autodma (was set by all host drivers - except HPT345/TRM290 special
  cases - unless "ide=nodma" was used).

While at it:
- remove needless printk() from icside.c
- remove stale FIXME/comment from ide-probe.c
- don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c
  (this setting was always later over-ridden by host drivers anyway)

c58e79dd44 ide: remove CONFIG_BLK_DEV_IDEDMA_FORCED
This code doesn't use pci_assign_resource() and ide_get_or_set_dma_base() uses
pci_resource_start() to get DMA base address so it has no chance of working.
Moreover this belongs to PCI quirks (in case somebody would like to fix it).

0ae2e17865 ide: remove ->ide_dma_check (take 2)
* Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend
  on BIOS for programming device/controller for DMA.  Set it in cy82c693,
  generic, ns87415, opti621 and trm290 host drivers.

* Add IDE_HFLAG_VDMA host flag for host drivers using VDMA.  Set it in cs5520
  host driver.

* Teach ide_tune_dma() about IDE_HFLAG_TRUST_BIOS_FOR_DMA flag.

* Add generic ide_dma_check() helper and remove all open coded ->ide_dma_check
  implementations.  Fix all places checking for presence of ->ide_dma_check
  hook to check for ->ide_dma_on instead.

* Remove no longer needed code from config_drive_for_dma().

* Make ide_tune_dma() static.

v2:
* Fix config_drive_for_dma() return values.

* Fix ide-dma.c build for CONFIG_BLK_DEV_IDEDMA_PCI=n by adding
  dummy config_drive_for_dma() inline.

* Fix IDE_HFLAG_TRUST_BIOS_FOR_DMA handling in ide_dma_check().

* Fix init_hwif_it8213() comment.

There should be no functionality changes caused by this patch.

c77a89cd98 sis5513: DMA setup fixes
* Add sis_ata133_get_base() helper function for obtaining the address of
  the drive control registers on chipset_family == ATA_133 chipsets.

* Add three helper functions for programming PIO/MWDMA timings:
  - sis_ata16_program_timings()  (for ATA_16/33/66/100a chipset families)
  - sis_ata100_program_timings() (for ATA_100/133a chipset families)
  - sis_ata133_program_timings() (for ATA_133 chipset family)

  MWDMA timings are taken from datasheets and they match ATA spec.

* Add generic helper function sis_program_timings() and use it in
  ->set_pio_mode and ->set_dma_mode methods (previously the driver
  depended on BIOS to program the correct MWDMA timings).

* Remove redundant !chipset_family check from init_hwif_sis5513()
  (init_chipset_sis5513() guarantees that we will never get here if
   chipset_family cannot be determined).

* SWDMA seems to be unsupported by SiS chipsets (no info about SWDMA in
  datasheets and for SWDMA0 mode timing requirements are impossible to
  fulfill) so remove ->swdma_mask from init_hwif_sis5513() and handling
  of SWDMA modes from sis_set_dma_mode().

* Enable DMA support for chipset_family == ATA_16.

* Bump driver version.

  the host for the transfer mode after programming the device.  Set it
  in au1xxx-ide, amd74xx, cs5530, cs5535, pdc202xx_new, sc1200, pmac
  and via82cxxx host drivers.

* Add IDE_HFLAG_NO_SET_MODE host flag to indicate the need to completely
  skip programming of host/device for the transfer mode ("smart" hosts).
  Set it in it821x host driver and check it in ide_tune_dma().

* Add ide_set_pio_mode()/ide_set_dma_mode() helpers and convert all
  direct ->set_pio_mode/->speedproc users to use these helpers.

* Move ide_config_drive_speed() calls from ->set_pio_mode/->speedproc
  methods to callers.

* Rename ->speedproc method to ->set_dma_mode, make it void and update
  all implementations accordingly.

* Update ide_set_xfer_rate() comments.

* Unexport ide_config_drive_speed().

v2:
* Fix issues noticed by Sergei:
  - export ide_set_dma_mode() instead of moving ->set_pio_mode abuse wrt
    to setting DMA modes from sc1200_set_pio_mode() to do_special()
  - check IDE_HFLAG_NO_SET_MODE in ide_tune_dma()
  - check for (hwif->set_pio_mode) == NULL in ide_set_pio_mode()
  - check for (hwif->set_dma_mode) == NULL in ide_set_dma_mode()
  - return -1 from ide_set_{pio,dma}_mode() if ->set_{pio,dma}_mode == NULL
  - don't set ->set_{pio,dma}_mode on it821x in "smart" mode
  - fix build problem in pmac.c
  - minor fixes in au1xxx-ide.c/cs5530.c/siimage.c

- HDIO_SET_PIO_MODE ioctl would now return -ENOSYS for attempts to change
  PIO mode if it821x controller is in "smart" mode
- removal of two debugging printk-s (from cs5530.c and sc1200.c)
- transfer modes 0x00-0x07 passed from user space may be programmed twice on
  the device (not really an issue since 0x00 is not supported correctly by
  any host driver ATM, 0x01 is not supported at all and 0x02-0x07 are invalid)

3b4024d429 amd74xx/via82cxxx: check ide_config_drive_speed() return value
* Check ide_config_drive_speed() return value.

* While at also call ide_config_drive_speed() if the transfer mode is
  XFER_PIO_SLOW (this case happens iff the transfer mode has already been
  set on the device by ide-proc.c::set_xfer_rate()) and remove redundant
  setting of ->{init,current}_speed.

* Bump driver version.

0f458943e0 au1xxx: fix au1xxx_set_pio_mode()
Set transfer mode on the device before programming the host controller for
the new timings (matches what auide_tune_chipset() is doing wrt DMA modes).

75d7d963e3 icside: use ide_tune_dma()
* Add "good DMA drives" hack for icside to ide-dma.c::ide_find_dma_mode()
  (in the long-term it should be either removed or generalized for all hosts).

* Use ide_tune_dma() in icside.c::icside_dma_check().

  This results in the following changes in behavior:
  - pre-EIDE SWDMA modes are now also respected
  - drive->autodma is checked instead of hwif->autodma
    (doesn't really matter as icside sets both to "1")

* Make ide-dma.c::__ide_dma_good_drive() static and drop "__" prefix.
