5bfb151f1f ide: do not access ide_drive_t 'drive_data' field directly
Change ide_drive_t 'drive_data' field from 'unsigned int' type to 'void *'
type, allowing a wider range of values/types to be stored in this field.

Added 'ide_get_drivedata' and 'ide_set_drivedata' helpers to get and set
the 'drive_data' field.

Fixed all host drivers to maintain coherency with the change in the
'drive_data' field type.

c9ef59ff01 ide: IORDY handling fixes
Add ide_pio_need_iordy() helper and convert host drivers to use it.

This fixes it8172, it8213, pdc202xx_old, piix, slc90e66 and siimage
host drivers to handle IORDY correctly.

74638c8482 ide: add support for CFA specified transfer modes (take 3)
Add support for the CompactFlash specific PIO modes 5/6 and MWDMA modes 3/4.

Since there were no PIO5 capable hard drives produced and one would also need
66 MHz IDE clock to actually get the difference WRT the address setup timings
programmed, I decided to simply replace the old non-standard PIO mode 5 timings
with the CFA specified ones.

35c9b4daf4 ide: add ->dma_clear method and remove ->dma_timeout one
All custom ->dma_timeout implementations call the generic one thus it is
possible to have only an optional method for resetting DMA engine instead:

* Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105
  host drivers to use it.

* Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
 ->dma_timeout method.

* Make ide_dma_timeout() static.

There should be no functional changes caused by this patch.

22117d6eaa ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)
* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it.

* Add ->dma_timer_expiry method and use it to set hwif->expiry for
  ATA_PROT_DMA protocol in do_rw_taskfile().

* Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts.

* Move setting hwif->expiry from ide_execute_command() to its users and drop
  'expiry' argument.

* Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile().

* Remove ->dma_exec_cmd method and its implementations.

* Unexport ide_execute_command() and ide_dma_intr().

v2:
* Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap).

* Fix *dma_expiry naming (suggested by Sergei Shtylyov).

There should be no functional changes caused by this patch.

2ed0ef543a ide: fix ->init_chipset method to return 'int' value
* Return 0 instead of dev->irq in ->init_chipset implementations.

* Fix ->init_chipset method to return 'int' value instead of
  'unsigned int' one.

This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.

592b531521 ide: move read_sff_dma_status() method to 'struct ide_dma_ops'
Move apparently misplaced read_sff_dma_status() method from 'struct ide_tp_ops'
to 'struct ide_dma_ops', renaming it to dma_sff_read_status() and making only
required for SFF-8038i compatible IDE controller drivers (greatly cutting down
the number of initializers) as its only user (outside ide-dma-sff.c and such
drivers) appears to be ide_pci_check_simplex() which is only called for such
controllers...
