in terms of hardware i have configured as per the clock configuration but if we see the above message i have a doubt regarding the 60x Bus Freq 16-50 --> but i have set 100 MHZ, Core Freq 50-150 , i have set for 300 MHZ by checking the MPC8280EC i have configured the clock settings.
It looks like the strings such as 16-50, 50-150, etc. are redundant (the computed value using clkin is also shown), unhelpful (it's not obvious that it's supposed to be a range -- and what is the range really supposed to tell you?), and just wrong (it assumes certain possible clkins).
Look at cpu_clk and bus_clk instead, which have the values you're expecting.
if anyone ported U-boot 1.3.1 on MPC8280 send me the u-boot messages when booted or power on.
Why use such old code?
