Robert Hancock 382a6652e9 sata_nv: use ADMA for NODATA commands ... Some problems showed up recently with cache flush commands timing out on sata_nv. Previously these commands were always handled by transitioning to legacy mode from ADMA mode first. The timeout problem was worked around already by a change to the interrupt handling code for legacy mode, but for non-data commands like these it appears we can handle them in ADMA mode, so the switch to legacy mode is not needed. This patch changes the behavior so that we use ADMA mode to submit interrupt-driven commands with ATA_PROT_NODATA protocol. In addition to avoiding the problem mentioned above entirely, this avoids the overhead of switching to legacy mode and back to ADMA mode for handling cache flushes. When handling non-DMA-mapped commands, we leave the APRD blank and clear the NV_CPB_CTL_APRD_VALID field in the CPB so the controller does not attempt to read it.
