* set to 0x0 in the internal buffer. If timeout_secs <= 0 then the timeout
* is set to 60 seconds. For data in or out transfers set dinp or doutp,
* and dlen to the number of bytes to transfer. If dlen is zero then no data
* transfer is assumed. If sense buffer obtained then it is written to
* sensep, else sensep[0] is set to 0x0. If ATA return descriptor is obtained
* then written to ata_return_dp, else ata_return_dp[0] is set to 0x0. Either
