ata_tf_load - send taskfile registers to host controller
void ata_tf_load (struct ata_port * ap,
const struct ata_taskfile * tf);
ap Port to which output is sent
tf ATA taskfile register set
Outputs ATA taskfile to standard ATA host controller using MMIO or PIO
as indicated by the ATA_FLAG_MMIO flag. Writes the control, feature,
nsect, lbal, lbam, and lbah registers. Optionally (ATA_TFLAG_LBA48)
writes hob_feature, hob_nsect, hob_lbal, hob_lbam, and hob_lbah.
This function waits for idle (!BUSY and !DRQ) after writing registers.
If the control register has a new value, this function also waits for
idle after writing control and before writing the remaining registers.
May be used as the tf_load entry in ata_port_operations.
Inherited from caller.
