[U-Boot] Low BogoMIPS on MPC8541

Hi All,

I'm working on a stripped-down mpc8541 board (that has just a serian and twe enets). I have an issue on delay calibration. In fact at boot time, I see the following linux printk message on the serial console:

.... Calibrating delay loop... 83.20 BogoMIPS (lpj=166400) ....

This value seems to be too low and I suspect an error propagated from u-boot.

Can anyone help me to understand a good way to investigate this problem? which registers or configuration values I need to check?

I will post the necessary snips of code or configuration if required.

Thanks a lot for your help,

ciao
