You don't plainly don't understand, because you just called ARM a platform. ARM isn't a platform, it's an architecture, which is a totally different thing. A platform is a device, like a phone, or a router, or a computer. However, all platforms may have the same CPU architecture - that being ARM. ARM as an architecture is in the situation where distributions have pushed hard for it to be like x86. You build one kernel for your distribution, not multiple hardware specific kernels. That means, there is one kernel configuration. Platform specifics are handled through firmware such as device tree. Having platform specific kernel configuration options, such as "we want to use PHY timestamping" vs "we want to use MAC timestamping" do not work in this environment. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
