Are you sure that 0x1ffc0000 is a correct address of for the
relocated image? Do you really have 512 MB of RAM on your system? And
does your U-Boot image really require exactly 256 kB of space?

Sounds like you are using bogus addresses.
#define DEBUG when compiling lib_ppc/board.c and check the output.
BTW: this discussion if off-topic in linuxppc-embedded; please post
any follow-ups to u-boot-users instead.
