      ide: add ide_host_add() helper · 6f904d01
      Bartlomiej Zolnierkiewicz authored
      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

      ide: add struct ide_host (take 3) · 48c3c107
      Bartlomiej Zolnierkiewicz authored
      * 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().
      * Add missing 'struct ide_host *host' to macide.c.
      * Fix build problem in pmac.c (s/ide_alloc_host/ide_host_alloc/)
        (Noticed by Stephen Rothwell).

      ide: pass hw_regs_t-s to ide_device_add[_all]() (take 3) · c97c6aca
      Bartlomiej Zolnierkiewicz authored
      * 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().
      * Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
        (Suggested by Geert Uytterhoeven)
      * Better patch description.
      * Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell)
      There should be no functional changes caused by this patch.

      ide: remove ->hold field from ide_hwif_t (take 2) · 2304dc64
      Bartlomiej Zolnierkiewicz authored
      ->hold is write-only now, remove it.
      * v1 missed bast-ide, palm_bk3710, ide-cs and delkin_cb host drivers.

      ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3) · 93de00fd
      Bartlomiej Zolnierkiewicz authored
      hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS
      and given the number of bugs we can assume that there are no real users:
      * DMA has no chance of working because DMA resources are released by
        ide_unregister() and they are never allocated again.
      * Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls
        don't work for almost all hosts with "non-standard" (== non ISA-like)
        layout of IDE taskfile registers (there is a lot of such host drivers).
      * ide_port_init_devices() is not called when probing IDE devices so:
        - drive->autotune is never set and IDE host/devices are not programmed
          for the correct PIO/DMA transfer modes (=> possible data corruption)
        - host specific I/O 32-bit and IRQ unmasking settings are not applied
          (=> possible data corruption)
        - host specific ->port_init_devs method is not called (=> no luck with
          ht6560b, qd65xx and opti621 host drivers)
      * ->rw_disk method is not preserved (=> no HPT3xxN chipsets support).
      * ->serialized flag is not preserved (=> possible data corruption when
         using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366
         (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers).
      * ->ack_intr method is not preserved (=> needed by ide-cris, buddha,
        gayle and macide host drivers).
      * ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it
        isn't initialized again (SiI3112 support needs them).
      * To issue an ioctl() there need to be at least one IDE device present
        in the system.
      * ->cable_detect method is not preserved + it is not called when probing
        IDE devices so cable detection is broken (however since DMA support is
        also broken it doesn't really matter ;-).
      * Some objects which may have already been freed in ide_unregister()
        are restored by ide_hwif_restore() (i.e. ->hwgroup).
      * ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[]
        slot cannot be found.
      * When IDE host drivers are modular unregistered port may be re-used by
        different host driver that owned it first causing subtle bugs.
      Since we now have a proper warm-plug support remove these ioctls,
      then remove no longer needed:
      - ide_register_hw() and ide_hwif_restore() functions
      - 'init_default' and 'restore' arguments of ide_unregister()
      - zeroeing of hwif->{dma,extra}_* fields in ide_unregister()
      As an added bonus IDE core code size shrinks by ~3kB (x86-32).
      * fix ide_unregister() arguments in cleanup_module() (Andrew Morton).
      * fix ide_unregister() arguments in palm_bk3710.c.
