Looking at the list of SoCs using Mali: https://en.wikipedia.org/wiki/Mali_(GPU) then clearly a lot of vendors could benefit from that.

Right, I suggested Odroid-U3 (with Mali 400 and Exynos4412) because the board works quite well with mainline. Most of stuff is upstreamed. However I am using Tizen TV profile (public) on it with 4.0 kernel (not entirely public). There are a lot of more devices with Mali 400 or newer so the question would be rather - which board would work the best (with less problems) on mainline. Anyway good luck :) Best regards, Krzysztof
