That's what it was for - a stop-gap for transitioning 32-bit ARM to DT. It shouldn't be extended to new platforms. No one answered my question whether there was a regression or whether this was for new platforms. Given that lack of engagement, I'm just going to say a flat NO to this, since we don't seem to be able to communicate effectively. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
