Yocto build broken due to branch deletion on github



Recently on github altera-opensource/linux-fpga several branches were deleted (including linux 4.2, 4,4, 4.1 ltssi etc.). Now our Yocto build is failing.

We are still using the 4.2 kernel and we used the Yocto build instructions published on Rocketboards. We do not want to update the kernel at this time.

Is it possible to restore the deleted banches?
