A-004510 can cause memory corruption due to dirty cache lines being dropped. The workaround in U-Boot reconfigures the chip so that this can't happen. The reconfiguration lasts until a reboot, so it's still effective once you start Linux. It needs to happen while there's no other traffic on the bus, which is why the workaround is not done in Linux itself. What revision of what chip are you using, and what version of U-Boot? -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
