[U-Boot-Users] MPC5200 XLB / IP Frequencies

Hi,

we are using u-boot on the MPC5200.
In the file "cpu_init.c" there is a comment: "Motorola reports IPB better 
run at 133MHz".
Does anyone know where this information can be found?
I tried to find a note in the errata (Rev 5 10/2004)  but found the 
following in support ID 412: 
"Use the clock ratio XLB : IP = 2 : 1" - and with XLB running at maximum 
132MHz it contradicts 
the statement that IP runs better at 133MHz.

Has anyone any ideas about how this mix together?

Thanks

Mats Larsson
