Yes, I am getting behind due to some 8xx MMU problems. If I am really lucky I may be able to do 83xx only, but my code base is a mess ATM :( > > > Um... jut to be sure - I understand that by "all architectures" above > you actually mean "all Power architecture CPU families", i. e. you > don't include the needed cleanup for ARM, MIPs, etc. here (yet) ? I sure hope so :) _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
