Some people prefer running a 32bit armhfp userland against the 64bit C2 aarch64 kernel, since some 64bit packages still suffer from performance / stability issues. Ubuntu and Debian support having packages from multiple architectures mixed up in one userland (multiarch), so its quite easy to run e.g. a 32bit Firefox browser within a 64bit xenial xerus. The kernel itself has to be 64bit, afaik.

At this time, the C2 kernel of choice is still a 3.14 vendor kernel from HK. Mainline boots up fine but crashes under some load. 

How about providing a sbc/board agnostic CentOS userland (like Jim did for aarch64, see http://mirror.centos.org/altarch/7/isos/aarch64/CentOS-7-aarch64-rootfs-1606.tar.xz)? I'd really appreciate it.

Cheers
Uli
