Where are previous (i.e., 2.6) kernel sources?

I need to build a custom 2.6 kernel. Where are the (git?) archives of PKGBUILD sources for previous kernels? For example, the most up-to-date 2.6 kernel? Otherwise, I can manually build a 2.6 kernel if I can download the necessary Arch Linux ARM patches.

For what device, we may have never built a package for that SoC
