Hi Alex,

Only with your patch, there will still be problem on SRIO platforms other than MPC85xx.

I have posted a patch series to fix this together with several compatibility issues a month before.


Can anyone pick the patch series quickly as currently there is a compile error when SRIO is enabled.
