RK3188 3D acceleration

[johnfulgor]

Hello all,
I've followed this step by step guide:
http://androtab.info/radxa_rock/mali/
but the openEGL test in sunxi-mali fails with "Error: eglInitialise failed!"
I've built all the modules against the kernel source code provided by olimex.
Has anyone made some experiments with mali on this board?
Thank you.
