I had a look at the recipe you referenced, and while it uses the
linux-yocto name, it isn't referencing the linux-yocto kernel tree or
a BSP definition in the tree. If it had referenced linux-yocto, I would
have been carrying the support forward to 3.8, 3.10, etc.

If you have a choice, I'd recommend 3.10 over 3.8 .. but you may not
have a choice.

Back to the point. In this case, your upgrade path would be to check
with the maintainer/author of the recipe and the renasas tree referenced
in that recipe. If they have something newer .. you are good to go,
otherwise, you'll need to see what sort of patches need to be ported
to uprev.

Cheers,

Bruce
