Look at the board information structure you are passing to linux. hh2.0
is expecting the cpu clock in HZ.
Look at commproc.c in arch/ppc/8260_io to see how the cpu freq is used
for baud rates.

Subject: HZ to MHZ, 2.4.2 kernel

I remember someone having a problem with the kernel using hz and
expecting MHZ or the other way around and it seems I'm running into this
problem right now.   Are there any patches or anything that address this
issue with regards to the 8260 serial and also the time.c code? This is
in HHL 2.0, 2.4.2 kernel
