I have a custom embedded system with a 440GP derived CPU that places the
memory starting at 0x10000000 which requires a non-zero PPC_MEMSTART.
I use denx linux kernel version is ARCH=powerpc. 
I set PPC_MEMSTART = 0x10000000(include/asm-powerpc/page_32.h)
I get boot linux message as follow:
RAMDISK driver initialized: 16 RAM disks of 8192K size 1024 blocksize
RAMDISK: Compressed image found at block 0
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: 128k init
init has generated signal 4 but has no handler for it
kernel panic - no syncing: Attempted to kill init!
Rebooting in 180 seconds..

How do I fix it?Do I miss anything?Thanks for your help ahead.
