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, --js
