Bartlomiej Zolnierkiewicz 255115fb35 ide: allow host drivers to specify IRQ flags
* Add ->irq_flags field to struct ide_port_info and struct ide_host.

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...

Bartlomiej Zolnierkiewicz 0d1bad216c ide: manage resources for PCI devices in ide_pci_enable() (take 3)
* Reserve PCI BARs 0-3 (0-1 for single port controllers) in
  ide_pci_enable() and remove ide_hwif_request_regions() call
  from ide_device_add_all() (also cleanup resource management
  in scc_pata host driver).

* Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup
  ide_iomio_dma() (+ init_hwif_trm290() in trm290 host driver)
  and remove ide_release[_iomio]_dma().

v2:
* Fixup trm290 host driver.

v3:
* Because of scc_pata host driver changes we need to call
  pci_request_selected_regions() also in setup_mmio_scc().

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.

Bartlomiej Zolnierkiewicz 5e71d9c5a5 ide: IDE_HFLAG_BOOTABLE -> IDE_HFLAG_NON_BOOTABLE
"bootable" should be the default behavior so replace
IDE_HFLAG_BOOTABLE host flag with IDE_HFLAG_NON_BOOTABLE.

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.

Bartlomiej Zolnierkiewicz f01674e459 ide: remove obsoleted "idex=noprobe" kernel parameter (take 2)
* Remove obsoleted "idex=noprobe" kernel parameter.

* Remove no longer needed hwif->noprobe quirk from ide_hwif_configure()
  and hwif->noprobe checking from cmd640.c.

v2:
* "ide?=noprobe" -> "ide?=ata66" in Documentation/kernel-parameters.txt.

Bartlomiej Zolnierkiewicz aab8ad9ec8 ide: remove needless hwif->irq check from ide_hwif_configure()
ide_init_default_irq() is always zero for CONFIG_PCI=y so hwif->irq
check in ide_hwif_configure() can be safely removed.
