Subject: ide: move ide_pci_setup_ports() call out from
 do_ide_setup_pci_device()

* Move ide_pci_setup_ports() call out from do_ide_setup_pci_device()
  to ide_setup_pci_device[s]().

* Drop no longer needed idx argument from do_ide_setup_pci_device().

There should be no functional changes caused by this patch.

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Wed, 23 Jul 2008 19:55:50 +0200
Subject: ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3)

* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
  host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use
  it instead of calling ide_init_port_hw() directly.

  [ However if host has > 1 port we must still set hwif->chipset to hint
    consecutive ide_find_port() call that the previous slot is occupied. ]

* Unexport ide_init_port_hw().

v2:
* Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
  (Suggested by Geert Uytterhoeven)

* Better patch description.

v3:
* Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell)

There should be no functional changes caused by this patch.

Subject: ide: factor out simplex handling from ide_pci_dma_base()

* Factor out simplex handling from ide_pci_dma_base() to
  ide_pci_check_simplex().

* Set hwif->dma_base early in ->init_dma method / ide_hwif_setup_dma()
  and reset it in ide_init_port() if DMA initialization fails.

* Use ->read_sff_dma_status instead of ->INB in ide_pci_dma_base().

There should be no functional changes caused by this patch.

* Set host driver specific hwif->tp_ops in ide_init_port().

* Export ide_exec_command(), ide_read_status(), ide_read_altstatus(),
  ide_read_sff_dma_status(), ide_set_irq(), ide_tf_{load,read}()
  and ata_{in,out}put_data().

* Convert host drivers and core code to use struct ide_tp_ops.

* Remove no longer needed default_hwif_transport().

* Cleanup ide_hwif_t from methods that are now in struct ide_tp_ops.

While at it:

* Use struct ide_port_info in falconide.c and q40ide.c.

* Rename ata_{in,out}put_data() to ide_{in,out}put_data().

v2:

* Fix missing convertion in ns87415.c.

There should be no functional changes caused by this patch.

From 48c3c1072651922ed153bcf0a33ea82cf20df390 Mon Sep 17 00:00:00 2001
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Wed, 23 Jul 2008 19:55:57 +0200
Subject: ide: add struct ide_host (take 3)

* Add struct ide_host which keeps pointers to host's ports.

* Add ide_host_alloc[_all]() and ide_host_remove() helpers.

* Pass 'struct ide_host *host' instead of 'u8 *idx' to
  ide_device_add[_all]() and rename it to ide_host_register[_all]().

* Convert host drivers and core code to use struct ide_host.

* Remove no longer needed ide_find_port().

* Make ide_find_port_slot() static.

* Unexport ide_unregister().

v2:
* Add missing 'struct ide_host *host' to macide.c.

v3:
* Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/)
  (Noticed by Stephen Rothwell).

From 6f904d015262dfa43eb1cecc00b0998b4c3543f2 Mon Sep 17 00:00:00 2001
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Wed, 23 Jul 2008 19:55:57 +0200
Subject: ide: add ide_host_add() helper

Add ide_host_add() helper which does ide_host_alloc()+ide_host_register(),
then convert ide_setup_pci_device[s](), ide_legacy_device_add() and some
host drivers to use it.

While at it:

* Fix ide_setup_pci_device[s](), ide_arm.c, gayle.c, ide-4drives.c,
  macide.c, q40ide.c, cmd640.c and cs5520.c to return correct error value.

* -ENOENT -> -ENOMEM in rapide.c, ide-h8300.c, ide-generic.c, au1xxx-ide.c
  and pmac.c

* -ENODEV -> -ENOMEM in palm_bk3710.c, ide_platform.c and delkin_cb.c

* -1 -> -ENOMEM in ide-pnp.c

Subject: ide: call ide_pci_setup_ports() before do_ide_setup_pci_device()

* Call ide_pci_setup_ports() before do_ide_setup_pci_device()
  in ide_setup_pci_device[s]().

While at it:

* Remove stale FIXMEs.

Subject: ide: add ->dev and ->host_priv fields to struct ide_host

* Add 'struct device *dev[2]' and 'void *host_priv' fields
  to struct ide_host.

* Set ->dev[] in ide_host_alloc_all()/ide_setup_pci_device[s]().

* Pass 'void *priv' argument to ide_setup_pci_device[s]()
  and use it to set ->host_priv.

* Set PCI dev's ->driver_data to point to the struct ide_host
  instance if PCI host driver wants to use ->host_priv.

* Rename ide_setup_pci_device[s]() to ide_pci_init_{one,two}().

Subject: ide: add ide_pci_remove() helper

* Add 'unsigned long host_flags' field to struct ide_host.

* Set ->host_flags in ide_host_alloc_all().

* Always set PCI dev's ->driver_data in ide_pci_init_{one,two}().

* Add ide_pci_remove() helper (the default implementation for
  struct pci_driver's ->remove method).

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Thu, 24 Jul 2008 22:53:31 +0200
Subject: ide: include PCI device name in messages from IDE PCI host drivers

While at it:

* Apply small fixes to messages (s/dma/DMA/, remove trailing '.', etc).

* Fix printk() call in ide_setup_pci_baseregs() to use KERN_INFO.

* Move printk() call from ide_pci_clear_simplex() to the caller.

* Cleanup do_ide_setup_pci_device() a bit.

* amd74xx.c: remove superfluous PCI device revision information.

* hpt366.c: fix two printk() calls in ->init_chipset to use KERN_INFO.

* pdc202xx_new.c: fix printk() call in ->init_chipset to use KERN_INFO.

* pdc202xx_old.c: fix driver message in pdc202xx_init_one().

* via82cxxx.c: fix driver warning message in via_init_one().
