Hi Brian,

That's great that Cirrus decided to merge its verion of buildroot with mainline.
I was thinking to start adding Cirrus stuff to buildroot by myself, because we use EP93xx
 but need packages present in mainline buildroot.

Now that's a good chance to join efforts so that Cirrus EP93xx integration into buildroot go quickly.

I'd suggest you to take a look into target/device dir
and create layout for target/device/Cirrus

And start posting your patches. I think patches for packages are not very Cirrus CPU specific.
