Improve support of OpenGL for BeagleBone Black
Make ti-gfx working on BeagleBone Black by adding an ugly necessary
patch to the kernel wich fix:
pvrsrvkm: Unknown symbol v7_dma_map_area
pvrsrvkm: Unknown symbol v7_dma_flush_range
Add drivers to the default kernel config used in beaglebone_defconfig
to enable the framebuffer.
