Well, Warp and Sam440EP are production boards for actual companies. The rest are all just eval boards. I don't know if the board maintainers care either way, I was just using them as examples of cases where someone might. > As for the other boards, I would like to wire them up if they are able > to support LE mode - If anyone has one handy I would love to hear if > they are able to begin booting a LE kernel with these patches, or when & > how they fail. I'd avoid anything with an FPU until that gets tested. So no bamboo, sequoia, canyonlands, etc. I noticed that canyonlands isn't even covered. I'm guessing that's because we don't need to create a wrapper for it because U-Boot does direct loading of vmlinux and the DTB itself. Has anyone done any work with getting U-Boot to work in LE mode or at least load LE vmlinux images? The majority of new boards are going to be using U-Boot and it's ability to load the DTB/FDT, so that would be something that needs addressing. josh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
