If you're doing PL111, then you might as well do PL110, because the two are basically the same. But note that all PL111's aren't equal. Some are closer to PL110 than the current PL111, so if you want to support all PL111s, you also need to have the support in place for PL110. Also note that the way the bits are assigned in the frame buffer varies between platforms, and most certainly the TRMs documentation of colour bitfield layouts can _not_ be relied upon. I have considerable knowledge in this area, but as seems to be the norm now, no one cares about that. I'll go back to twiddling my thumbs now, waiting for the next email to arrive. Or maybe I'll go down to the shops and wander around down there. Or something. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
