http://linux-sunxi.org/SATA looks relevant...

http://dl.cubieforums.com/files/pdf/A10_development_board_user_manual--2011.9.23_English.pdf
mentions the feature list:

The board provides one SATA interface, which features:
- Support SATA 1.5Gb/s, and SATA 3.0Gb/s
- Compliant to SATA Spec. 2.6, and AHCI Revision 1.3 Specifications
- Support industry-standard AMBA High-Performance Bus (AHB) and fully
compliant to the AMBA Specification, Revision 2.0; Support 32-bit Little
Endian
- OOB signaling detection and generation
- SATA 1.5Gb/s and SATA 3.0Gb/s speed negotiation when Tx OOB signaling
is selected
- Support device hot-plugging
- Support power management features including automatic Partial to
Slumber transition
- Internal DMA Engine for Command and Data Transactions
- Support hardware-assisted Native Command Queuing (NCQ) for up to
32-entries
- Support external SATA (eSATA)

I can't find anything else, though. I'll just have to wait from Peter to
see what registers he needed to modify to get it working.

Thanks,
