Subject: ide: add ->chipset field to ide_pci_device_t

Add ->chipset field to ide_pci_device_t and use it in ide_hwif_configure()
to set hwif->chipset.  Convert cmd64x, cy82c693, rz1000 and trm290 host
drivers to use this new ability.

While at it define hwif_chipset_t as u8 to save some space in hw_regs_t,
ide_hwif_t and ide_pci_device_t instances.

Subject: ide: add IDE_HFLAG_FORCE_LEGACY_IRQS host flag

Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag to tell ide_pci_setup_ports()
to always set hwif->irq to legacy IRQ 14/15 and convert generic IDE PCI
and via82cxxx host drivers to use it.

While at it:

* Add IDE_HFLAGS_UMC define (generic IDE PCI host driver).

* Remove no longer needed init_hwif_generic() (generic IDE PCI host driver).

* Set d->udma_mask instead of hwif->ultra_mask (via82cxxx host driver).

Subject: ide: add IDE_HFLAG_{IO_32BIT,UNMASK_IRQS} host flags

Add IDE_HFLAG_{IO_32BIT,UNMASK_IRQS} host flag to tell ide_pci_setup_ports()
to set drive->{io_32bit,unmask} for both drives on the interface.  Convert
amd74xx, sl82c105 and via82cxxx host drivers to use these new host flags.

While at it:

* Add IDE_HFLAGS_AMD define (amd74xx host driver).

* Add IDE_HFLAGS_VIA define (via82cxxx host driver).

Subject: alim15x3: fix CD_ROM DMA and PIO FIFO settings setup

* Setup CD_ROM DMA and PIO FIFO settings in init_chipset_ali15x3() instead
  of ata66_ali15x3().  The latter is called from init_hwif_common_ali15x3()
  only if DMA base exists (which insists m5529_revision > 0x20).

  This changes makes CD_ROM DMA / PIO FIFO bits being set only once
  and also when "idex=ata66" kernel parameter is used.

* While at it move also chip_is_1543c_e setup from ata66_ali15x3() to
  init_chipset_ali15x3() and check if isa_dev exists before accessing it.

* Bump driver version.

Subject: siimage: separate PATA and SATA methods

* Split off sil_sata_udma_filter() from sil_udma_filter()
  and rename sil_udma_filter() to sil_pata_udma_filter().

* Rename siimage_busproc() to sil_sata_busproc().

* Rename siimage_reset_poll() to sil_sata_reset_poll()
  and in init_hwif_siimage() set ->reset_poll method only
  for SATA controllers.

* Rename siimage_pre_reset() to sil_sata_pre_reset(),
  in init_hwif_siimage() set ->pre_reset method only for
  SATA controllers and remove redundant is_sata() call.

* Add CONFIG_BLK_DEV_IDE_SATA #ifdef/#endif to pdev_is_sata()
  so compiler will know to throw out unused SATA code for
  CONFIG_BLK_DEV_IDE_SATA=n case (830 bytes saved on x86-32).

* Bump driver version.

Some minor cleanups while at it:

* Convert sil_{pata,sata}_udma_filter() to use ATA_UDMA* defines.

* In siimage_mmio_ide_dma_test_irq() move 'base' variable
  under 'if (SATA_ERROR_REG)' block.

* Simplify sil_sata_reset_poll() a bit.

* Cache is_sata() result in init_hwif_siimage()

Subject: ide: add ->fixup method to ide_hwif_t

* Add ->fixup method to ide_hwif_t.

* Set hwif->fixup in ide_pci_setup_ports() to d->fixup.

* Use hwif->fixup in probe_hwif().

* Use probe_hwif_init() instead of probe_hwif_init_with_fixup() in
  ide_setup_pci_device().

* Add 'fixup' argument to ide_register_hw() and use it to set hwif->fixup,
  update all ide_register_hw() users accordingly.

* Convert ide-cs/delkin_cb host drivers to use ide_register_hw().

* Restore hwif->fixup in ide_hwif_restore().

* Remove ide_register_hw_with_fixup(), probe_hwif_init_with_fixup()
  and 'fixup' argument from probe_hwif().

From 8447d9d52adbe4c653482bd0d5ccb9b5d26f9c9d Mon Sep 17 00:00:00 2001
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Sat, 20 Oct 2007 00:32:31 +0200
Subject: ide: add ide_device_add()

* Add ide_device_add() helper and convert host drivers to use it
  instead of open-coded variants.

* Make ide_pci_setup_ports() and do_ide_setup_pci_device()
  take 'u8 *idx' argument instead of 'ata_index_t *index'.

* Remove no longer needed ata_index_t.

* Unexport probe_hwif_init() and make it static.

* Unexport ide_proc_register_port().

There should be no functionality changes caused by this patch
(sgiioc4.c: ide_proc_register_port() requires hwif->present
 to be set and it won't be set if probe_hwif_init() fails).

Add CONFIG_IDE_ARCH_OBSOLETE_INIT to drivers/ide/Kconfig and use it instead
of defining IDE_ARCH_OBSOLETE_INIT in <arch/ide.h>.

Subject: ide: fix ide_register_hw() to check hwif->io_ports[]

hwif->hw.io_ports[] and hwif->io_ports[] should be the same but "4drives"
support and scc_pata host driver set only hwif->io_ports[].

To compensate for this check hwif->io_ports[] instead of hwif->hw.io_ports[]
in ide_register_hw() (instead of fixing "4drives" and scc_pata because hwif->hw
is to be removed).

Subject: icside: use ec->dma directly

* hwif->hwif_data contains pointer to struct expansion_card so use ec->dma
  directly instead of caching it in hwif->hw.dma.

* Remove no longer needed hw_regs_t.dma and NO_DMA define.

Fixes same issue as fixed by Alan Cox in atiixp host driver with
commit 6c5f8cc33eb2e10b6ab788bbe259fc142a068627.

cmd640 is a bit special cause we still need to leave ide_lock for
->set_pio_mode with 'pio' argument == 8/9 (prefetch disable/enable).

Subject: ht6560b: fix deadlock on error handling

Stop abusing ide_lock lock (switch to a private locking).

Fixes same issue as fixed by Alan Cox in atiixp host driver with
commit 6c5f8cc33eb2e10b6ab788bbe259fc142a068627.

ht6560b is a bit special cause we still need to leave ide_lock for
->set_pio_mode with 'pio' argument == 8/9 (prefetch disable/enable).

Subject: ide: PCI BMDMA initialization fixes (take 2)

* Set hwif->dma_base only if allocation of extra ports succeeds.

While at it:

* Move setting of hwif->dma_{base,master} from ide_{mapped_mmio,iomio}_dma()
  to ide_setup_dma().

* Rename 'dma_base' argument to 'base' in ide_setup_dma() (to make the code
  obey 80-columns limit and increase its readability).

* Remove stale ide_setup_dma() comment.

v2:
* Change to allocate hwif->dmatable_cpu before reserving I/O ports missed
  teardown code (spotted by Sergei).  On the second thought this change is
  actually unnecessary so revert it in v2.

* Make ide_release_dma_engine() void and remove needless comment.

Subject: qd65xx: remove pointless qd_{read,write}_reg() (take 2)

These functions are atomic so locking is pointless (noticed by Sergei).

v2:
We can now just use local_irq_save/restore() in qd_testreg() (noticed by Jeff).

It should be TASKFILE_NO_DATA, not TASKFILE_IN.  Luckily ATM ->data_phase is
unused if ->command_type == IDE_DRIVE_TASK_NO_DATA but this may change in the
future.
