I think it's just these two: http://git.openrisc.net/cgit.cgi/jonas/linux/commit/?id=fb6e2e42c8d56d7c8f47828bc2d96950be1f58b9 http://git.openrisc.net/cgit.cgi/jonas/linux/commit/?id=ba55149979f383504fd5a566d61c75555fe7de88 > Which branch in your linux tree is the most stable/usable one? I try to keep the master branch usable... it's 3.3-rc3, but it's all in good working order. Aside from that, I'm currently working in aac-3.2... there are some additional drivers there and a couple of patches that will soon go into the master branch... nothing really interesting, but if you want to use u-boot there's support for building 'uImage' in that tree. As for uClibc, here's the branch with the patches needed to work with the upstream kernel. Caveat emptor: these weren't really liked by upstream uClibc... help in getting that sorted out would be appreciated. http://git.openrisc.net/cgit.cgi/jonas/uClibc/log/?h=syscall-fixups-uClibc-master Hope that helps... > > > I've got a patch series that attempts to fix that, but upstream uClibc > > didn't seem particularly enamored by the idea of adding more code to > > libc so that Linux can get smaller... and that's kind of where we got > > stuck. > > BTW: What about glibc? There is no openrisc port to glibc. The big blocker here is that glibc is difficult/impossible to build without having proper support for dynamic linking... The current openrisc toolchain lacks support for PIC and, consequently, shared objects. /Jonas
