The mpc85xx_defconfig does include silicons with e500v1 core which doesn't have the 36-bit support. Won't enabling 36-bit support by default break the support for them? - Leo _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
