Ubuntu on Arria 10 SoC


I was made aware that the Arria 10 does not natively support Ubuntu 16.04 . I am trying to boot Ubuntu on the on board ARM via microSD card. I have looked at the following tutorial ( https://rocketboards.org/foswiki/Documentation/UbuntuCoreForSoCFPGAArrowSoCKit) but was wondering if there was a better explanation on how to get the required files as well as what these files do ?

Thank you.
