    ide: fix UDMA/MWDMA/SWDMA masks (v3) · 18137207
    Bartlomiej Zolnierkiewicz authored
    * use 0x00 instead of 0x80 to disable ->{ultra,mwdma,swdma}_mask
    * add udma_mask field to ide_pci_device_t and use it to initialize
      ->ultra_mask in aec62xx, cmd64x, pdc202xx_{new,old} and piix drivers
    * fix UDMA masks to match with chipset specific *_ratemask()
      (alim15x3, hpt366, serverworks and siimage drivers need UDMA mask
       filtering method - done in the next patch)
    
    v2:
    * piix: fix cable detection for 82801AA_1 and 82372FB_1
      [ Noticed by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ]
    * cmd64x: use hwif->cds->udma_mask
      [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ]
    * aec62xx: fix newly introduced bug - check DMA status not command register
      [ Noticed by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ]
    
    v3:
    * piix: use hwif->cds->udma_mask
      [ Suggested by Sergei Shtylyov <sshtylyov@ru.mvista.com>. ]
