Re: [PATCH v1 2/5] ixp4xx: Resurrect IXP4xx support using device tree
Thanks for reviewing this Hauke! I fixed most things, will post v2 as time permits.

Yes it was one of the leftovers that just stayed around after the removal of the unmaintained ixp4xx boardfile machines. So I just select it from the top-level makefile and things work fine. Another thing left behind was the python build script for NSLU2 images. But I needed them so it's all good when we bring IXP4xx back. (Please don't delete them...) I deleted one minor useless script though (patch 5). Yours, Linus Walleij ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
