No. The kernel will detect at runtime that that it's an e500v1 core and it won't try to create 36-bit TLBs. (e.g. it won't write to MAS7). Please remember that the Kconfig for the P1022DS already forced PHYS_64BIT for all mpc85xx platforms. All we're doing is making it possible to deselect PHYS_64BIT. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
