Usually they are hidden behind a raid engine, or they are intended for use in software RAID. As such, Marvell absolutely does not provide programming specs on these chips, so writing a open source driver is impossible. FreeBSD does have support for the Highpoint flavor of Marvell software RAID, so you might be able to coerce the pci attach code in that driver to think that your chip is a highpoint product. The better approach would probably be to find out how your supplier got ahold of this chip and what the intended function/purpose of the chip is, then contact the sub-vendor that is responsbile for that function. There are also possibilities in reverse engineering, but I'm tainted on Marvell and cannot comment further. Scott
