I can easily test for Tegra3 architecture but I have no more Tegra2
devices. It was a old Tegra2 patch I have done few month ago that was
working and I have updated for the Tegra3.

So if anyone would like to help for Tegra2, from my side I going to
look if I can get another Tegra2 device.

I saw your patch and the GL header comes from the revision 23432 except
for the eglplatform.h that comes from revision 12306. I doesn't know
exactly why but it's what was provided by the Nvidia partner that does
the tegra device I use.

I have just seen that NVidia has released the V16.5 of Linux4Tegra for
The Tegra3 only and it's exclusively distributed via NVIDIA's partner
portal but it's only fix on memory leaks in gstreamer plugins.
