Well at least you can have a common image for all U-Boot boards :) I suppose the 64-byte header per-board would work. Ugly, but not as ugly as some of the other options. You could also make a small mod to U-Boot to allow the load address of legacy images to be changed via a command to make the hack slightly less ugly Regards, Graeme _______________________________________________ arm mailing list arm@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/arm
