cuImage not building

Hi,

I have gotten our MPC8347 based board to work under Linux-2.6.27.1.

Since our board is similar to mpc834x_mds, I initially modified files relevant
to mpc834x_mds to get our board working.

Now I'm trying to rename files so that they reflect our board names.

After this renaming, uImage gets built ok, but cuImage build fails. 
I enabled make's verbose flag to see what was going on
and here are the error messages

+ powerpc-unknown-linux-gnu-ld -m elf32ppc -T arch/powerpc/boot/zImage.lds -Ttext 0x400000 --defsym _start=0x400000 -o arch/ppc/boot/cuImage.snsp arch/powerpc/boot/cuboot-snsp.o ./zImage.15886.o arch/powerpc/boot/wrapper.a
powerpc-unknown-linux-gnu-ld: arch/powerpc/boot/cuboot-snsp.o: No such file: No such file or directory

Here is the build invocation with mpc834x_mds files.

+ powerpc-unknown-linux-gnu-ld -m elf32ppc -T arch/powerpc/boot/zImage.lds -Ttext 0x400000 --defsym _start=0x400000 -o arch/ppc/boot/cuImage.mpc834x_mds arch/powerpc/boot/cuboot-83xx.o ./zImage.3158.o arch/powerpc/boot/wrapper.a

From the two invocations, not working code gets called with arch/powerpc/boot/cuboot-snsp.o

whereas working code gets called with arch/powerpc/boot/cuboot-83xx.o.

I have made relevant changes to appropriate Makefiles, but I still cant get cuImage to build.

can someone help?
thanks a lot
