Just wanna to confirm one thing. If one board's 
SDRAM init was good enough but with poor layout
(Layout design or PCB Processing), it would crash
like this? Could it boot after relocation? 

I know my assumption isn't reasonable. Well, I have
a similar experience on 823. That board could only
get the output before relocation in u-boot. Never 
for booting Linux. After a fix on some pull-ups 
around CPU and good PCB processing, it worked fine.

So I can make sure one thing. Not all crash after 
relocation is due to SDRAM init. That's just our 
software engineer/developer can do. Perhaps it is 
related with mini error on schematic design or PCB 
layout including processing. 

A little bit out of topic. Sorry for this:-)
