I'm afraid there is no such one. That family of controllers is neither
mvs(4) nor ahci(4). It is completely separate design, providing quite
low-level interface to SAS ports (that means that support for wide
ports, expanders, target mapping, etc. should be done manually inside
the driver). I had a wish to implement it at some point, but had no
documentation. Now I have some documentation and even some (old now)
hardware, but not sure how much widespread/applicable are those chips
now. Complains like that happen not so often and I am not sure I want to
spend few months of work on discontinued hardware. Has Marvell released
anything new from that line, like 12Gbps SAS, that could be interesting?
