Description
The Marvell 88SE9128 AHCI Controller was suffering by the same bug as ASMedia ASM1062, i.e. 64-bit writes to PxCLB, PxCLBU, PxFB, and PxFBU failed - see Bug #3797. After the fix the 88SE9128 started to work somehow, but unreliably. Sometime the attached disks were detected, but usually not.
In general, the port reset (in function ahci_port_reset) is failing.
The problem is that the ahci_port_reset() does not follow the port reset sequence as documented in the AHCI spec, section 10.4.2.

There are few other issues with 88SE9128:
- According to information from Marvell at http://www.marvell.com/storage/system-solutions/assets/Marvell-88SE91XX-Product-Brief.pdf the controller supports 2 SATA ports, but both PI (Ports Implemented) and CAP.NP exposes 8 ports (we will not fix/workaround this issue here)
- There is special device connected to port 7 of this controller, it is ATAPI processor. We are adding basic support for this device into the sata driver as well.
