This box has A80, right? If so, you're out of luck. It would require considerable effort on kernel side - HDMI, VPU and I2S drivers are missing and DMA driver status is unknown (nobody tested it). IIRC also display driver might not be good enough. Biggest showstopper is that it uses PowerVR GPU, for which there are no driver which would work with GBM interface (requirement for LibreELEC). Some months ago there was one person from PowerVR on #linux-sunxi IRC, who claimed that wants provide such blob, but I don't think anything happened.
EDIT: By missing I mean that very similar drivers already exist, but they need A80 specific adjustments.
