So you obviously have either some hardware problem with your RAM,
and/or bugs in your RAM init code.
we can see from the out put, u-boot can recognize the frequence of the momery, and more info. through spd.
How can we do to fix this problem?
Review the hardware and your chnages to the code.
we use MT9VDDT1672AG first, then, KVR400X64C3A, both can't work.

then it can't go on running. we checked ,found it falled in "relocate_code" ,then we write a progam to test memory, we found test failed(say write some thing to 0-0x8000000 then read)
