PS reading in the FSF website: "The AllWinner Axx and R8 platforms come in
many boards such as the A13-OLinuXino, Cubieboard, Gooseberry, Hackberry and
CHIP.
While there is free 2D acceleration for Xorg, the GPU and the some features
of the video encoding/decoding (VPU) hardware are unusable in the free world,
so these jobs must be done on the CPU. In particular, the VPU cannot encode
videos and can only decode videos in a few MPEG formats."
It appears that no hardware support for some functionalities. I expect the
same for other arm based chips.
