Given that syscfg0 is a shared register, are we sure the code that updates this register is safe from races caused by two MACs going through the config progress in two separate CPUs at the same time? Is there anything which prevents two or more MACs wanting to mess with the contents of the SYSCFG0_SGMII_MASK bits? It's difficult to tell with the current code. Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
