You cannot solve  these  problems  by  downgrading  to  PPCBoot.  The
852/859/866  processors  are  definitelu *not* supported by PPCBoot -
the required changes of the clock handling were added much later. You
*must* use U-Boot.

You mean you shipped boards to customers in  the  field  in  a  state
where you did not even decide for a final version of the boot loader?
Gosh...

U-Boot is running perfectly fine on the TQM859 - we have these boards
here in our virtual lab; they are tested on a regular base.

I can *guarantee* you that PPCBoot is definitely worse on your hardware.

u-boot-users
