Honored ContributorI built buildroot and u-boot from alteras repository on github. Now I want to build linux but there is no config file for ep4ce115 linux config. How can I continue?
$ ls
buildroot linux-socfpga u-boot-socfpga
Honored ContributorAs far as I know, unfortunately there is no config file for DE2-115. You may want to try 3c120, but I am not sure if that will work

i can confirm that it works now.
I could build and start the latest version of linux-socfpga. It took some time to understand the parameters. Now I get a nice login shell and can login with the password that I set in buildroot. There was no need for special configuration files, I could use the nios2-generic everywhere for the DE2-115. The startup log has some small mysteries what it means and I'm going to investigate it. For now I'm really glad that the kernel worked with DE2-115. It's version 4.9 from the github repository that I used. The boot sequence looks according to the following:
