To a limited extent. The accelerated graphics on ARM (and cell phones) has always been a system integrator problem. Until very recently, they were not user customizable - which means the initialisation was part of the proprietary firmware and hard to port across even different implementations of the same SoC. The x86 world had the advantage of user upgradable GPUs, which necessitates standardization and common firmware. On top of which, the accelerated graphics of cell phones is a horrible kludge of various standards.
