[fedora-arm] Cubieboard 5 (aka CubieTruck Plus)

Hi there, now the board is on my table. The only image i've found is linaro-desktop-cubietruck-plus-card-dp-v1.1.img. But I don't think its a real aarch64 Image: linaro@cubietruck-plus:~$ uname -a Linux cubietruck-plus 3.4.39 #7 SMP PREEMPT Tue Mar 1 09:34:33 CST 2016 armv7l armv7l armv7l GNU/Linux linaro@cubietruck-plus:~$ I think this should be armv8l ? Is there any howto to create/build a aarch64 Image on a Cubieboard 5 with Fedora ? Greetings Andreas
