Did you use CONFIG_PPC_CPM_NEW_BINDING in 2.6.25? It became mandatory in
2.6.26. Also, try commenting out cpm_setbrg() calls in case the
frequency is not being set properly.
2.6.26 introduced the allocation of the CPM2 SMC parameter RAM area; what
did your device node look like in 2.6.25? What happens if you use that
device tree with 2.6.26?
