This causes a stand alone kernel defconfig build of stmark2 to fail with:

...
  CC      init/calibrate.o
  CC      init/init_task.o
  AR      init/built-in.o
  HOSTCC  usr/gen_init_cpio
  ./scripts/gen_initramfs_list.sh: Cannot open '../uClinux-dist/romfs'
make[1]: *** [usr/initramfs_data.cpio.gz] Error 1
make: *** [usr] Error 2

Obviously in a stand alone build you cannot rely on any directory
paths outside of the kernel tree.

The simple solution is just to remove this CONFIG_INITRAMFS_SOURCE
line - and that results in complete build. Of course it won't
work on your target as expected though.

Other ColdFire defconfigs don't use an init ramfs, instead using
a local ram based MTD partition. 

Do you want to come up with a patch to fix this?
Otherwise I will create a patch that just removes that one line.

Regards
Greg
