You need to modify the base address of the each node to map in to processor
address space. All device nodes in device tree are provisioned with
physical addresses in processor domain. You need to understand the device
tree structure. Check your specs regarding the I/O mapping of the processor

I am using the defconfig from linux kernel tree and for CCSR in u-boot its
F800 so the same i am using in device tree... so my question is - is it
unable to parse device tree ? or in device tree some thing need to modify
in device tree or in kernel source...
please give some light on this...
Why do not you use deconfig from linux kernel tree. Modify only base
address of CCSR (soc node) for child nodes of root in device tree.

i tried to dig more inside mpic_alloc fails. the function
of_find_matching_node calls inside from mpic_alloc() should return the node
at which pic is connected but it returns NULL. but why? In device tree i am
using the following.. may be it will helpful.
/dts-v1/;

Hi,
I was trying to port Linux-3.12 for MPC8641 based custom designed board for
evaluation purpose. I have been facing a kernel bug at mpic initialization.
Is somebody have faced this kind of bugs or can give me any pointer for
further steps how to solve kernel bugs will be really helpful. here is
