adb1af9803 ide: pass command instead of request to ide_pio_datablock()
* Add IDE_TFLAG_FS taskfile flag and set it for REQ_TYPE_FS requests.

* Convert ->{in,out}put_data methods to take command instead of request
  as an argument.  Then convert pre_task_out_intr(), task_end_request(),
  task_error(), task_in_unexpected(), ide_pio_sector(), ide_pio_multi()
  and ide_pio_datablock() in similar way.

* Rename task_end_request() to ide_finish_cmd().

There should be no functional changes caused by this patch.

22aa4b32a1 ide: remove ide_task_t typedef
While at it:
- rename struct ide_task_s to struct ide_cmd
- remove stale comments from idedisk_{read_native,set}_max_address()
- drop unused 'cmd' argument from ide_{cmd,task}_ioctl()
- drop unused 'task' argument from tx4939ide_tf_load_fixup()
- rename ide_complete_task() to ide_complete_cmd()
- use consistent naming for struct ide_cmd variables

There should be no functional changes caused by this patch.

19710d25d5 ide: add "flagged" taskfile flags to struct ide_taskfile (v2)
* Add ->ftf_flags field to struct ide_taskfile
  and convert flags for TASKFILE ioctl to use it.

* Rename "flagged" taskfile flags:
  - IDE_TFLAG_FLAGGED -> IDE_FTFLAG_FLAGGED
  - IDE_TFLAG_FLAGGED_SET_IN_FLAGS -> IDE_FTFLAG_SET_IN_FLAGS
  - IDE_TFLAG_{OUT,IN}_DATA -> IDE_FTFLAG_{OUT,IN}_DATA

v2:
* Remember to fully update ide-h8300.c, scc_pata.c and tx493{8,9}ide.c
  (thanks to Stephen Rothwell for noticing).

There should be no functional changes caused by this patch.

6e5f1e1115 ide: add at91_ide driver
This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory
Controller with Compact Flash True IDE Mode logic.

Driver have to switch 8/16 bit bus width when accessing Task Tile or Data
Register. Moreover some extra things need to be done when setting PIO mode.
Only PIO mode is used, hardware have no DMA support. If interrupt line is
connected through GPIO extra quirk is needed to cope with fake interrupts.
