The A20 supports PMP, just remove the Flag AHCI_HFLAG_NO_PMP in the sunxi ahci driver. Please take a look in the Manual of the A20 (6.15.1). The SATA interface has the following specification: Comply with SATA Spec. 2.6, and AHCI Revision 1.3 specifications
This includes the PMP support. We are using a Marvel PMP and it works fine - both disks are detected and work. Regards Tobias Am Dienstag, 23.
