2008-04-26ide: factor out setting PCI bus-mastering from ide_hwif_setup_dma()Bartlomiej Zolnierkiewicz
Factor out setting PCI bus-mastering from ide_hwif_setup_dma() to ide_pci_set_master() helper. While at it: * don't read PCI Command register if not necessary * use PCI device name instead of hwif->name * cleanup ide_hwif_setup_dma() a bit Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: export ide_allocate_dma_engine()Bartlomiej Zolnierkiewicz
Export ide_allocate_dma_engine() and use it in trm290 host driver. Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: move ide_setup_dma() call out from ->init_dma methodBartlomiej Zolnierkiewicz

2008-04-26alim15x3: skip DMA initialization completely on revs < 0x20Bartlomiej Zolnierkiewicz
Skip DMA initialization completely on revs < 0x20 by setting IDE_HFLAG_NO_DMA host flag and resetting DMA host masks in alim15x3_init_one() (currently ide_hwif_setup_dma() will try to obtain DMA base and setup PCI bus-mastering but init_dma_ali15x3() will fail).

2008-04-26pdc202xx_old: remove init_dma_pdc202xx()Bartlomiej Zolnierkiewicz

2008-04-26ide: don't display "BIOS" settings in ide_setup_dma()Bartlomiej Zolnierkiewicz
Nowadays BIOS info is not very useful and only confuses users since: - IDE always tries to use DMA - BIOS info may not be accurate with modular IDE/libata Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: remove ->cds field from ide_hwif_t (take 2)Bartlomiej Zolnierkiewicz
* Use hwif->name instead of cds->name in ide_allocate_dma_engine(). * Use pci_name(dev) instead of cds->name in init_dma_pdc202xx(). * Remove no longer needed ->cds field from ide_hwif_t. v2: * scc_pata.c also needs to be updated now (noticed by Stephen Rothwell). There should be no functional changes caused by this patch.

2008-04-26ide: remove ide_dma_iobase()Bartlomiej Zolnierkiewicz
* ide_mapped_mmio_dma() and ide_iomio_dma() are called only by ide_dma_iobase() so inline them there. * ide_dma_iobase() is called only by ide_setup_dma() so inline it there. * Setup hwif->extra_base also if hwif->mmio flag is set. There should be no functional changes casued by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-04-26ide: remove ->extra field from struct ide_port_infoBartlomiej Zolnierkiewicz

2008-04-26ide: cleanup setting hwif->mmio flagBartlomiej Zolnierkiewicz
It is no longer needed to set hwif->mmio flag to tell IDE layer to not manage resources so cleanup host drivers that used hwif->mmio flag only for this purpose. Ditto for ide_legacy_init_one(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
