Hello,
I am bootstrapping an mpc5121e board.
When the cpu speed is calculated (cpu/mpc512x/speed.c) there is a comment about
all core pll settings above 7 are invalid....
I can't see anything about that in the CPU documentation so I am wondering if
anyone has reference to where this is defined as invalid.
The board I am using is using CORE PLL index 0x8, i.e. multiplier of 4.
If this comment in the code is wrong then the following patch should be o.k...
Index: cpu/mpc512x/speed.c
