However, this can be something that might take time to support in CCF (I definetly have plans to send a RFC to, at least, start the discussion around this) so I guess we can already support this device like this. I believe this is somethig straight to remove as soon as CCF works in 32bit archs for high speed devices... - Nuno Sá
