2007-10-20typo fixesMatt LaPlante
Most of these fixes were already submitted for old kernel versions, and were approved, but for some reason they never made it into the releases. Because this is a consolidation of a couple old missed patches, it touches both Kconfigs and documentation texts.

2007-10-20ide: fix ->data_phase in taskfile_load_raw()Bartlomiej Zolnierkiewicz
It should be TASKFILE_NO_DATA, not TASKFILE_IN. Luckily ATM ->data_phase is unused if ->command_type == IDE_DRIVE_TASK_NO_DATA but this may change in the future. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-10-20qd65xx: remove pointless qd_{read,write}_reg() (take 2)Bartlomiej Zolnierkiewicz
These functions are atomic so locking is pointless (noticed by Sergei). v2: We can now just use local_irq_save/restore() in qd_testreg() (noticed by Jeff).

2007-10-20ide: PCI BMDMA initialization fixes (take 2)Bartlomiej Zolnierkiewicz
* Set hwif->dma_base only if allocation of extra ports succeeds. While at it: * Move setting of hwif->dma_{base,master} from ide_{mapped_mmio,iomio}_dma() to ide_setup_dma(). * Rename 'dma_base' argument to 'base' in ide_setup_dma() (to make the code obey 80-columns limit and increase its readability). * Remove stale ide_setup_dma() comment. v2: * Change to allocate hwif->dmatable_cpu before reserving I/O ports missed teardown code (spotted by Sergei). On the second thought this change is actually unnecessary so revert it in v2. * Make ide_release_dma_engine() void and remove needless comment.

Fixes same issue as fixed by Alan Cox in atiixp host driver with commit 6c5f8cc33eb2e10b6ab788bbe259fc142a068627. ht6560b is a bit special cause we still need to leave ide_lock for ->set_pio_mode with 'pio' argument == 8/9 (prefetch disable/enable).

2007-10-20ide: fix ide_register_hw() to check hwif->io_ports[]Bartlomiej Zolnierkiewicz
hwif->hw.io_ports[] and hwif->io_ports[] should be the same but "4drives" support and scc_pata host driver set only hwif->io_ports[]. To compensate for this check hwif->io_ports[] instead of hwif->hw.io_ports[] in ide_register_hw() (instead of fixing "4drives" and scc_pata because hwif->hw is to be removed).

* Add ide_device_add() helper and convert host drivers to use it instead of open-coded variants. * Make ide_pci_setup_ports() and do_ide_setup_pci_device() take 'u8 *idx' argument instead of 'ata_index_t *index'. * Remove no longer needed ata_index_t. * Unexport probe_hwif_init() and make it static. * Unexport ide_proc_register_port(). There should be no functionality changes caused by this patch (sgiioc4.c: ide_proc_register_port() requires hwif->present to be set and it won't be set if probe_hwif_init() fails).

Some minor cleanups while at it: * Convert sil_{pata,sata}_udma_filter() to use ATA_UDMA* defines. * In siimage_mmio_ide_dma_test_irq() move 'base' variable under 'if (SATA_ERROR_REG)' block. * Simplify sil_sata_reset_poll() a bit. * Cache is_sata() result in init_hwif_siimage() Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Make a local copy of ali15x3_chipset in alim15x3_init_one() and set ->host_flags / ->udma_mask according to the controller capabilities. * Cleanup init_hwif_common_ali15x3(). * Bump driver version. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-10-20alim15x3: fix CD_ROM DMA and PIO FIFO settings setupBartlomiej Zolnierkiewicz
* Setup CD_ROM DMA and PIO FIFO settings in init_chipset_ali15x3() instead of ata66_ali15x3(). The latter is called from init_hwif_common_ali15x3() only if DMA base exists (which insists m5529_revision > 0x20). This changes makes CD_ROM DMA / PIO FIFO bits being set only once and also when "idex=ata66" kernel parameter is used. * While at it move also chip_is_1543c_e setup from ata66_ali15x3() to init_chipset_ali15x3() and check if isa_dev exists before accessing it. * Bump driver version.

2007-10-20ide: add IDE_HFLAG_FORCE_LEGACY_IRQS host flagBartlomiej Zolnierkiewicz
Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag to tell ide_pci_setup_ports() to always set hwif->irq to legacy IRQ 14/15 and convert generic IDE PCI and via82cxxx host drivers to use it. While at it: * Add IDE_HFLAGS_UMC define (generic IDE PCI host driver). * Remove no longer needed init_hwif_generic() (generic IDE PCI host driver). * Set d->udma_mask instead of hwif->ultra_mask (via82cxxx host driver).
