Yes, you are right. Linux's cpufreq-pxa2xx.c always sets the turbo bit. However, if CONFIG_CPU_FREQ is not set (my case), bootloader's settings are used. I work on a system that has focus on low latency (industrial controller) rather than battery life (since it has no battery). _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
