Please remember that at least for T20 and T30 NVIDIA's officially
supported Linux for Tegra (L4T) is still based on the ancient Linux
kernel 3.1.10 relying on ATAGs. While Colibri T20 and Apalis/Colibri
T30 are mainline since a while there is still no solution for hardware
accelerated graphics/multimedia compatible with mainline as far as I
know. So for hardware accelerated graphics/multimedia one is pretty
much stuck with L4T requiring ATAGs!
