Marvell's approach to data makes it (almost?) impossible to use them in an open source project.
The bastards bought the Stongarm PXA2xx from Intel, and locked it right down, after we were shipping. (I have a long memory...)
Every encounter I've had with them (in the annoying thousands, but not hundreds of thousands volumes) has been a tedious crapfest of NDAs and still inadequate documentation, which had to be wrested from them, page by page. They're right at the bottom of the pile, when it comes to choosing chips, for me. Maybe I was just doing it wrong? Hints would be welcome, they've often got silicon that looks tempting, but I just can't be arsed any more.
The Soap boys are well out of it if they can avoid Marvell, in my opinion.
