i think this marvell media vault soc has quite a bit of
promise. this product seems to be an arm core + a mashup
of other marvell parts. the sata controller appears to have
the same register interfaces as the one driven by sdmv50xx.c.
the ethernet controller is not currently supported, but there
appears to be enough documentation to support it. (as
an added bonus, though i haven't had a chance to check in
detail, i would guess this would help support x86 marvell lom
parts (mv643xx) as well!)

the "User Manual" has all the crunchy register specs.
here's a few products based on this soc:

it would be so much nicer running a plan 9.
