[U-Boot] MPC8641D stucks before relocation

[Ashish Khetan]

hii I am using MPC8641D based custom board for evaluation purpose. I am
using minimal configuration for this board i.e. only FLASH and DDR
initialisation. when I compiled U-boot in debug mode its printing
addresses, i check for those addresses and found that it is unable to
relocate itself to DDR(4*MT47H64M16). The following message was printed...
