We already have arch/powerpc/configs/ppc40x_defconfig and arch/powerpc/configs/ppc44x_defconfig in mainline. What's wrong with using these? [Marri] Great we already have it. We should remove the defconfigs under 44x then ? Regards, Marri ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

Just make sure that it is minimal by using make savedefconfig. This will create a file defconfig in the current directory which should have the minimal amount of stuff in it to reproduce the current .config. -- Cheers, Stephen Rothwells...@canb.auug.org.au http://www.canb.auug.org.au/~sfr/ pgpha4DcBvzEZ.pgp Description: PGP signature ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

RE: Combining defconfigs for 44x based boards
Linus made a suggestion to that effect? If so, I missed it. Have a pointer? There was discussion going on in arm-kernel mailing list. And I see some patches being submitted for ARM based boards. I think we can also combine some of the defconfigs under arch/powerpc/configs/44x/ directory. Here is ARM dfconfigs discussion http://lkml.indiana.edu/hypermail/linux/kernel/1006.0/01464.html Here is the link for some of the defconfig submissions http://www.spinics.net/lists/arm-kernel/msg96972.html ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev

ARM and powerpc are somewhat different in this aspect, since ARM traditionally has not been able to build multiplatform kernels (especially not multi-soc-family kernels). Powerpc can build a kernel that will boot on all machines of a certain class (server, fsl-booke, ibm-booke, ppc32). So there's not really a whole lot of reason to have the custom per-board defconfigs in the kernel tree any more. For specific products it might still make sense for a vendor to make a custom minimal defconfig, but that doesn't mean it's a requirement to have them in the upstream repository. -Olof ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
