Re: Re[2]: How to change Bus speed for MPC8xx CPU

In message [ref] you wrote:

As far as I understand there is a bootloader provided by board
manufacturer this is something like BIOS in desktop pc.
And there should be part of the kernel running before
the kernel starts. So which one of them do the job with
clocks? Or probably both of them.

Normally the clocks are set in the bootloader only.

Linux does not change these parameters.

And there the kernel loader sources are located under
/usr/src/linux tree. I would like to put my patch inside and paly
with it.

My board is runnig from external clock of 10M and boot monitor
has parameter called mulitplier which is equal to 10.

So it seems there is  no  patch  needed  at  all.  Just  change  this
"multiplier" parameter.
