But this region of flash is marked as suitable for execute-in-place, otherwise the point() function wouldn't be working to give a direct pointer to it. It sounds like we shouldn't be allowing that. Which in turn means that perhaps we should have a property in the corresponding node in the device-tree which indicates that it's not suitable for direct access? -- dwmw2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
