The device tree describes the hardware, not what you want to do with it. The presence of the erratum itself is indicated by the presence of the buggy device, possibly in conjunction with SVR if the device tree is not specific enough. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
