Hi Chunrong,

I updated to the latest u-boot and got the same results ( hangs during 
kernel boot ).

It's 2.0 silicon ( DCFG_CCSR_SVR =  0x87081120 ).

I put the kernel debugger on it briefly today and verified that the 
kernel did panic / crash during boot before dumping to the terminal.  
I'll dig in further in the coming days to see where the panic occurs and 
report back.  I'll appreciate any guidance.

BTW, I'm using RSR_PPS_70/rcw_1000.bin and didn't change it from the 4.1 
linux-qoriq kernel.

Thank you,

Bob
