It is generally the responsibility of the kernel to enable the FPU for tasks which require it, allowing lazy save/restore of the FPU state on context switching. Enabling the FPU in u-boot might interfere with this. -- Måns Rullgård [email protected] _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
