Linux on a RK3368 eReader

Hello! There is a new eReader on the market called Boyue Likebook Mars. It has the processor RK3368, so its a Octa-core with 2 Gb of RAM, and it seems very promising, but Boyue did a mess with the firmware, making it so limited. So maybe there is the oportunity to install linux there.

I searched and I found a project on github talking about this, but not on an eReader. Aparently there are some Android TV Boxes with the same specs, and they can install linux there. I can imagine it should not be so easy as to just install it on the eReader, but maybe more than the half of the work is done with this github project. (I can't write the adress because I am new here, but it's easy to find if you google "linux rk3368")

Can anyone who understand all this world better than me (not so hard to happen) explain me a little about this possibility? I think maybe the more problematic thing it would be the eInk display.

Thanks in advance to everyone
