Bartlomiej Zolnierkiewicz fe80b937c9 ide: merge ide_match_hwif() and ide_find_port()
* Change ide_match_hwif() argument from 'u8 bootable' to
  'struct ide_port_info *d'.

* Move ide_match_hwif() to ide-probe.c from setup-pci.c and rename
  it to ide_find_port_slot().  Update some comments while at it.

* ide_find_port() can be now just a wrapper for ide_find_port_slot().

There should be no functional changes caused by this patch.

Sergei Shtylyov 1baccff8a5 ide: make ide_pci_check_iomem() actually work
This function didn't actually check if a given BAR is in I/O space because of
using the bogus PCI_BASE_ADDRESS_IO_MASK (which equals ~3) to test the resource
flags instead of IORESOURCE_IO -- fix this, make ide_hwif_configure() check the
results failing if necessary, and move the printk() call to the failure path.

* Remove 'struct pci_dev *dev' argument from ide_hwif_setup_dma().

* Un-static ide_hwif_setup_dma() and add CONFIG_BLK_DEV_IDEDMA_PCI=n version.

* Add 'const struct ide_port_info *d' argument to ide_device_add[_all]().

* Factor out generic ports init from ide_pci_setup_ports() to ide_init_port(),
  move it to ide-probe.c and call it in in ide_device_add_all() instead of
  ide_pci_setup_ports().

* Move ->mate setup to ide_device_add_all() from ide_port_init().

* Add IDE_HFLAG_NO_AUTOTUNE host flag for host drivers that don't enable
  ->autotune currently.

* Setup hwif->chipset in ide_init_port() but iff pi->chipset is set
  (to not override setup done by ide_hwif_configure()).

* Add ETRAX host handling to ide_device_add_all().

* cmd640.c: set IDE_HFLAG_ABUSE_* also for CONFIG_BLK_DEV_CMD640_ENHANCED=n.

* pmac.c: make pmac_ide_setup_dma() return an error value and move DMA masks
  setup to pmac_ide_setup_device().

* Add 'struct ide_port_info' instances to legacy host drivers, pass them to
  ide_device_add() calls and then remove open-coded ports initialization.

Benjamin Herrenschmidt 0948391641 PCI: Remove users of pci_enable_device_bars()
This patch converts users of pci_enable_device_bars() to the new
pci_enable_device_{io,mem} interface.

The new API fits nicely, except maybe for the QLA case where a bit of
code re-organization might be a good idea but I prefer sticking to the
simple patch as I don't have hardware to test on.

I'll also need some feedback on the cs5520 change.

* Make remaining built-in only IDE host drivers modular, add ide-scan-pci.c
  file for probing PCI host drivers registered with IDE core (special case
  for built-in IDE and CONFIG_IDEPCI_PCIBUS_ORDER=y) and then take care of
  the ordering in which all IDE host drivers are probed when IDE is built-in
  during link time.

* Move probing of gayle, falconide, macide, q40ide and buddha (m68k arch
  specific) host drivers, before PCI ones (no PCI on m68k), ide-cris (cris
  arch specific), cmd640 (x86 arch specific) and pmac (ppc arch specific).

* Move probing of ide-cris (cris arch specific) host driver before cmd640
  (x86 arch specific).

* Move probing of mpc8xx (ppc specific) host driver before ide-pnp (depends
  on ISA and none of ppc platform that use mpc8xx supports ISA) and ide-h8300
  (h8300 arch specific).

* Add "probe_vlb" kernel parameter to cmd640 host driver and update
  Documentation/ide.txt accordingly.

* Make IDE_ARM config option visible so it can also be disabled if needed.

* Remove bogus comment from ide.c while at it.

v2:
* Fix two issues spotted by Sergei:
  - replace ENOMEM error value by ENOENT in ide-h8300 host driver
  - fix MODULE_PARM_DESC() in cmd640 host driver

* Add VDMA check to ide_config_drive_speed().

* drive->using_dma was never enabled since cs5520 host driver's

  __ide_dma_on() was never called, drive->using_dma was never set

Bartlomiej Zolnierkiewicz 1c51361a98 ide: add IDE_HFLAG_SERIALIZE host flag
Add IDE_HFLAG_SERIALIZE host flag to tell ide_pci_setup_ports() to set
hwif/mate->serialized and convert aec62xx, cs5530 and sc1200 host drivers
to use it.

Bartlomiej Zolnierkiewicz 31e8a465a2 ide: use I/O ops directly part #2 (take 2)
v2:
- bump host driver versions (as suggested by Sergei)
- use I/O ops directly in drivers/ide/setup-pci.c

Bartlomiej Zolnierkiewicz fc212bb1fb ide: use pci_dev->revision
Some places were using PCI_CLASS_REVISION instead of PCI_REVISION_ID so
they were not converted by commit 44c10138fd.

Bartlomiej Zolnierkiewicz 5f8b6c3485 ide: add ->mwdma_mask and ->swdma_mask to ide_pci_device_t (take 2)
* Add ->mwdma_mask and ->swdma_mask to ide_pci_device_t.

* Set ide_hwif_t DMA masks using DMA masks from ide_pci_device_t in
  setup-pci.c::ide_pci_setup_ports() (iff DMA base is valid and ->init_hwif
  method may still override them).

* Convert IDE PCI host drivers to use ide_pci_device_t DMA masks.

While at it:

* Use ATA_{UDMA,MWDMA,SWDMA}* defines.

* hpt34x.c: add separate ide_pci_device_t instances for HPT343 and HPT345.

* serverworks.c: fix DMA masks being set before checking DMA base.

v2:
* Add missing masks to DECLARE_GENERIC_PCI_DEV() macro.

Bartlomiej Zolnierkiewicz 9ffcf364f9 ide: remove ->init_setup_dma from ide_pci_device_t (take 2)
* Make ide_pci_device_t.host_flags u32 and add IDE_HFLAG_CS5520 host flag.

* Pass ide_pci_device_t *d to setup-pci.c::ide_get_or_set_dma_base()
  and use d->name instead of hwif->cds->name.

* Set IDE_HFLAG_CS5520 host flag in cs5520 host driver and use it in
  ide_get_or_set_dma_base() to find out which PCI BAR to use, remove no longer
  needed cs5520.c::cs5520_init_setup_dma() and ide_pci_device_t.init_setup_dma.

  This fixes PCI bus-mastering not being checked for CS5510/CS5520 hosts.

v2:
* It is wrong to check simplex bits on CS5510/CS5520 as v1 did.

Add IDE_HFLAG_NO_{DMA,AUTODMA} host flags.  Convert all host drivers using
ide_pci_device_t to use these flags instead of d->autodma and then remove no
longer needed d->autodma.

Bartlomiej Zolnierkiewicz 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)

Bartlomiej Zolnierkiewicz 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).
