* No hardware documentation available outside of NVIDIA.
* This driver programs the NVIDIA SATA controller in a similar
* fashion as with other PCI IDE BMDMA controllers, with a few
* NV-specific details such as register offsets, SATA phy location,
* hotplug info, etc.
*
* CK804/MCP04 controllers support an alternate programming interface
* similar to the ADMA specification (with some modifications).
* This allows the use of NCQ. Non-DMA-mapped ATA commands are still
* sent through the legacy interface.
