I don't know if a separate set of flags is needed, but we probably want separate OBJS/SRCS lists. The dependencies are going to be different based on which toolchain you use, even if the flags are the same. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
