4.5-rc4 kernel is failed to bootup on CN6880

[Yang Shi]

Hi David,

I tried to boot 4.5-rc4 kernel on my CN6880 board, but it is failed at 
booting up secondary cores. The error is:

CPU31 revision is: 000d9101 (Cavium Octeon II)
SMP: Booting CPU32 (CoreId 32)...
Secondary boot timeout

I passed "numcores=32" in kernel commandline since there are 32 cores 
ion CN6880. And, the bootloader information is as below:

U-Boot 2013.07 ( (U-BOOT build: 104, SDK version: 3.1.1-544),
