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.

It is vxWorks bootrom. I could not (don't know) pass boot line
into linux. This is the default boot line.
# cat /proc/cmdline
root=/dev/nfs rw ip=auto

If you are using EST8260 as your board type, then you are using the embedded
boot loader. Look in embed_config.c

It works after I changed bd->bi_busfreq = 66 in embed_config.c .
It even clear my UART baud rate confusion.
Thanks.
