Dear All,
As a result of my mistake I've sent this patch with an incorrect SOB chain.
Please kindly disregard this patch.
@Neil: thank you for your time you spent reviewing it and answering and I'm
sorry it's to no effect.
@Ezequiel, @Tomeu: I apologize to you. My mistake.
Regards,
Andrzej Pietrasiewicz

It helps reduce memory bandwidth of the graphics pipeline operations.
This, in turn, improves power efficiency.
