  • The IDE code assumed for years that the bit 1 of the identify data word 53 also
    covers the validity of the SW/MW DMA information in words 62 and 63, but it has
    always covered only words 64 thru 70, with words 62 and 63 being defined in the
    original ATA spec, not in ATA-2...

    This fix however should only concern *very* old hard disks and rather old CF
    cards...

  • Set/clear drive->waiting_for_dma flag in the core code
    instead of in ->dma_setup and ->dma_end methods.

    There should be no functional changes caused by this patch.

  • Move ide_map_sg() call from ->dma_setup implementations and
    ide_destroy_dmatable() one from *_build_dmatable() to ide_dma_prepare().

    There should be no functional changes caused by this patch.

    Sergei:
    Removed 'use_pio_instead' labels and replaced 'goto' with 'return 0' --
    that required no changes to the follow-up patches...

  • Move ide_destroy_dmatable() call out from ->dma_end method to
    {ide_pc,cdrom_newpc,ide_dma}_intr(), ide_dma_timeout_retry()
    and sgiioc4_resetproc().

    This causes minor/safe behavior changes w.r.t.:
    * cmd64x.c::cmd64{8,x}_dma_end()
    * cs5536.c::cs5536_dma_end()
    * icside.c::icside_dma_end()
    * it821x.c::it821x_dma_end()
    * scc_pata.c::__scc_dma_end()
    * sl82c105.c::sl82c105_dma_end()
    * tx4939ide.c::tx4939ide_dma_end()

    v2:
    * Fix build for CONFIG_BLK_DEV_IDEDMA=n (reported by Randy Dunlap).

  • All custom ->dma_timeout implementations call the generic one thus it is
    possible to have only an optional method for resetting DMA engine instead:

    * Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105
    host drivers to use it.

    * Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
    ->dma_timeout method.

    * Make ide_dma_timeout() static.

    There should be no functional changes caused by this patch.

  • * Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it.

    * Add ->dma_timer_expiry method and use it to set hwif->expiry for
    ATA_PROT_DMA protocol in do_rw_taskfile().

    * Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts.

    * Move setting hwif->expiry from ide_execute_command() to its users and drop
    'expiry' argument.

    * Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile().

    * Remove ->dma_exec_cmd method and its implementations.

    * Unexport ide_execute_command() and ide_dma_intr().

    v2:
    * Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap).

    * Fix *dma_expiry naming (suggested by Sergei Shtylyov).

    There should be no functional changes caused by this patch.

  • * Set IDE_TFLAG_WRITE flag and ->rq also for ATA_CMD_PACKET
    commands.

    * Pass command to ->dma_setup method and update all its
    implementations accordingly.

    * Pass command instead of request to ide_build_sglist(),
    *_build_dmatable() and ide_map_sg().

    While at it:

    * Fix scc_dma_setup() documentation + use ATA_DMA_WR define.

    * Rename sgiioc4_build_dma_table() to sgiioc4_build_dmatable(),
    change return value type to 'int' and drop unused 'ddir'
    argument.

    * Do some minor cleanups in [tx4939]ide_dma_setup().

    There should be no functional changes caused by this patch.

  • 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...

    ide_remove_port_from_hwgroup() and ide_ports[].

    * Remove now unused HWGROUP() macro.

    While at it:
