It's entirely possible to build one kernel that supports the EBSA285, NetWinder and Compaq Personal Server. They're all the same machine at the end of the day (PCI based SA110.) As long as the boot loaders pass the correct machine type, the correct board file will be selected to set things up. However, if I remember correctly, Compaq seemed to be anti-mainline, so didn't implement the machine ID and other things. I ended up implementing a shim around the kernel to make mainline bootable on the platform to correct the stuff that they couldn't be bothered to implement. I may be adversely blaming them, as history from back then is rather fuzzy, but I do remember mainline doesn't work because of all sorts of weirdness they did. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
