/*
sata_mv TODO list:
1) Needs a full errata audit for all chipsets. I implemented most
of the errata workarounds found in the Marvell vendor driver, but
I distinctly remember a couple workarounds (one related to PCI-X)
are still needed.
2) Convert to LibATA new EH. Required for hotplug, NCQ, and sane
probing/error handling in general. MUST HAVE.
3) Add hotplug support (easy, once new-EH support appears)
4) Add NCQ support (easy to intermediate, once new-EH support appears)
5) Investigate problems with PCI Message Signalled Interrupts (MSI).
6) Add port multiplier support (intermediate)
7) Test and verify 3.0 Gbps support
8) Develop a low-power-consumption strategy, and implement it.
9) [Experiment, low priority] See if ATAPI can be supported using
"unknown FIS" or "vendor-specific FIS" support, or something creative
like that.
10) [Experiment, low priority] Investigate interrupt coalescing.
Quite often, especially with PCI Message Signalled Interrupts (MSI),
the overhead reduced by interrupt mitigation is quite often not
worth the latency cost.
11) [Experiment, Marvell value added] Is it possible to use target
mode to cross-connect two Linux boxes with Marvell cards? If so,
creating LibATA target mode support would be very interesting.
Target mode, for those without docs, is the ability to directly
connect two SATA controllers.
13) Verify that 7042 is fully supported. I only have a 6042.
