This shouldn't involve much more complexity than adding a small amount of init, which you'd need for the POST anyway. On cores that don't have FP, use soft float, and don't include the FPU POST code. This should not be any different than today, except for adding another compiler flag that depends on the build target. -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
