8260 core/bus/cpm clock

From: Yu Bo-BOYU1 <hidden>

After dumping cpu information,

# cat /proc/cpuinfo
cpu             : 82xx
core clock      : 132 MHz
CPM  clock      : 66 MHz
bus  clock      : 33 MHz
revision        : 1.1 (pvr 0081 0101)
bogomips        : 54.88

I found this is NOT correct for the custom board. It should be
66/133/166MHZ. However
I did not find any configurable entry in "make xconfig".

Thanks.

Bo

What is your bootloader? Some loaders pass this information to the kernel at
boot.
