This is probably no longer supported, but I have been searching the internet for a while and there are claims that the manufacturer source codes were handed over to netbsd. Perhaps I would be lucky enough that one of you know how I might compile or find/download a kernel for Marvell Armada 510 (88AP510) SoC with an ARM v6/v7-compliant superscalar processor core. It is an original cubox with 1gig of ram.
