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
