Framebuffer console has nothing do do with etnaviv. The framebuffer is
provided by imx-drm and has no acceleration capabilities.

Other than that, GC2000 and GC320 are well supported with etnaviv.

Please enable CONFIG_CMA.

In general the imx_v6_v7_defconfig should be a good starting point. It
enables way too much stuff for a single board, but it at least provides
a sane set of defaults.
