_start symbol contains only 32-bit data number 0x27051956 despite it is marked as text section. This magic number is IH_MAGIC which is used for marking uboot image header.
mpc85xx start.S code does not define valid uboot image header, so IH_MAGIC number in _start symbol is useless there.
Moreover this _start symbol is not used at all. Entry point is at symbol _start_e500.
So because this _start symbol is not used for anything, completely remove it with IH_MAGIC number. After _start symbol was _start_cont symbol, so replace all relative address calculations by _start_cont.
