The problem with most of these is availability of a Linux operating system image that is as mature, and close to 'stock' debian as raspbian is. Usually it's some two year old version of Ubuntu that's been cobbled together by the vendor.
I believe there's been some work in the this space by the Armbian[1] community, which is aiming to create a unified base distro for a wide range of ARM single-board computers including Odroid, Pine64, etc.
