    ata: Report 16/32bit PIO as best we can · e3cf95dd
    Alan Cox authored
    The legacy old IDE ioctl API for this is a bit primitive so we try
    and map stuff sensibly onto it.
    
    - Set PIO over DMA devices to report 32bit
    - Add ability to change the PIO32 settings if the controller permits it
    - Add that functionality into the sff drivers
    - Add that functionality into the VLB legacy driver
    - Turn on the 32bit PIO on the ninja32 and add support there
