No, it would not prevent *importing* it, as the CC BY-SA licenses are forward-compatible.
However, it would prevent *exporting* material from the Coreboot wiki to a CC BY-SA 3.0-licensed resource.
N.B. I might have used "forward-compatible" incorrectly above (perhaps it should have been "backward-compatible"? I get those terms mixed up...). Everything else there is correct, though. In short, CC BY-SA-licensed material under a given version of that license can be re-used under the same or later versions of the license but not under earlier versions of the license. (I'm assuming all the other requirements of the license are complied with.)
