Maybe some kind of new support has been added, but no one has told the arm developers, and thus bits needed for it aren't present. Honestly, I'm not going to worry about it. If someone wishes to contribute 32-bit arm support, then fine, otherwise I'll just ignore this. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
