    [libata] update IDENTIFY DEVICE path to use ata_queued_cmd · 5158abe2
    Jeff Garzik authored
    rather than hand-rolling our own taskfile call (which won't work at
    all on newer SATA controllers).
    
    Individual changes:
    * use ata_qc_issue to issue identify-device command
    * implement MMIO path for PIO data xfer
    * implement PIO error handling path
