2008-02-01ide: fix handling of busy I/O resources in probe_hwif()Bartlomiej Zolnierkiewicz
It could be that I/O resources are busy because some other host driver has already claimed them so don't unregister the devices. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-01ide: delete filenames/versions from commentsBartlomiej Zolnierkiewicz
Delete filenames/versions from comments. I'm leaving decisions about adding DRV_VERSION defines and MODULE_VERSION()-s to maintainers of the respective drivers. While at it: * Remove unused VERSION define from ide.c. * Remove unused/stale DRV_VERSION define from au1xxx-ide.c. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Add missing hw.dev setup (so hwif->gendev.parent will be set by ide_init_port_hw() to point to the parent device). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-01ide: use ide_build_sglist() and ide_destroy_dmatable() in non-PCI host driversBartlomiej Zolnierkiewicz
* Make ide_build_sglist() and ide_destroy_dmatable() available also when CONFIG_BLK_DEV_IDEDMA_PCI=n. * Use ide_build_sglist() and ide_destroy_dmatable() in {ics,au1xxx-}ide.c and remove no longer needed {ics,au}ide_build_sglist(). There should be no functionality changes caused by this patch. Cc: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-02-01ide: switch to DMA-mapping APIBartlomiej Zolnierkiewicz
* pci_map_sg() -> dma_map_sg() in ide_build_sglist(). * pci_unmap_sg() -> dma_unmap_sg() in ide_destroy_dmatable(). There should be no functionality changes caused by this patch except for blackfin arch whose dma_[un]map_sg() implementation differs from pci_[un]map_sg() one (on s390 arch there is no PCI, on avr32 and h8300 archs PCI is currently unsupported, on m32r arch PCI support depends on BROKEN, on m68k arch PCI support depends on HADES which in turn depends on BROKEN, on all other archs dma_[un]map_sg() functionality matches with pci_[un]map_sg() one). blackfin behavior change was ack-ed by Bryan Wu.

2008-02-01ide: keep pointer to struct device instead of struct pci_dev in ide_hwif_tBartlomiej Zolnierkiewicz
Keep pointer to struct device instead of struct pci_dev in ide_hwif_t. While on it: * Use *dev->dma_mask instead of pci_dev->dma_mask in ide_toggle_bounce(). There should be no functionality changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-02-01ide: add IDE_HFLAG_NO_DSC host flagBartlomiej Zolnierkiewicz
* Add IDE_HFLAG_NO_DSC host flag for hosts that doesn't support DSC overlap. * Set it in aec62xx (for ATP850UF only) and hpt34x host drivers. * Convert ide-tape device driver to check for IDE_HFLAG_NO_DSC flag.

2008-02-01ide: add IDE_HFLAG_CLEAR_SIMPLEX host flagBartlomiej Zolnierkiewicz
* Rename 'simplex_stat' variable to 'dma_stat' in ide_get_or_set_dma_base(). * Factor out code for forcing host out of "simplex" mode from ide_get_or_set_dma_base() to ide_pci_clear_simplex() helper. * Add IDE_HFLAG_CLEAR_SIMPLEX host flag and set it in alim15x3 (for M5229), amd74xx (for AMD 7409), cmd64x (for CMD643), generic (for Netcell) and serverworks (for CSB5) host drivers. * Make ide_get_or_set_dma_base() test for IDE_HFLAG_CLEAR_SIMPLEX host flag instead of checking dev->device (BTW the code was buggy because it didn't check for dev->vendor, luckily none of these PCI Device IDs was used by some other vendor for PCI IDE controller).

2008-02-01amd74xx: remove amd_ide_chips tableBartlomiej Zolnierkiewicz
* Remove no longer needed assertion from amd74xx_probe(). * Factor out cable detection for AMD7409 to amd7409_cable_detect() and for chipsets >= AMD7411 to amd7411_cable_detect(). * Use dev->vendor and dev->device instead of amd_config->udma_mask when selecting cable detection method and checking for broken FIFO support in init_chipset_amd74xx(). * Remove no longer needed AMD_BAD_FIFO define. * Add 'swdma' parameter for setting .swdma_mask to DECLARE_AMD_DEV() macro. * Add 'udma' parameter for setting .udma_mask to DECLARE_{AMD,NV}_DEV() macro. * Keep a copy of a current amd74xx_chipsets[] entry in amd74xx_probe() in order to fix ->swdma_mask on early AMD7409 revisions and ->udma_mask on Serenade mainboards. * Remove no longer needed fixups from init_chipset_amd74xx() and AMD_CHECK_{SWDMA,SERENADE} defines. * Move printing banner message from init_chipset_amd74xx() to amd74xx_probe(), also remove incorrect comment while at it. * Use hwif->ultra_mask instead of amd_config->udma_mask in amd_set_drive(). * Add 'udma_mask' argument to amd_set_speed() and pass UDMA mask from amd_set_drive() instead of using amd_config->udma_mask. * Move amd_config->base from AMD_* defines to users of these defines and add 0x40 the defined values. Then add amd_offset() inline helper for selecting offset from 0x40 base (needed for nVidia controllers) and finally use it in amd_set_speed(), amd7411_cable_detect() and init_chipset_amd74xx() instead of amd_config->base. * Remove no longer needed AMD_BAD_SWDMA define, ->{swdma,ultra}_mask setup from init_hwif_amd74xx(), amd_{config,chipset} variables and amd_ide_chips table. * Fix init_chipset_amd74xx() comment. * Bump driver version.
