socfpga arria10 "CPU1: failed to come online"

Hi

When my system is started, I found that there will be two problems. The first problem is that only CPU0 can be online for dual-core and CPU1 is Offline. The second problem is that although CPU0 is started, BogoMIPS is only 100MHZ, and our hardware configuration is 800MHZ. What's the problem?

The following is the environment I use, and the attachment is the detailed configuration parameters.

I am using Socfpga arria10
The linux kernel uses 4.9.78-ltsi
uboot uses 2014.10

You can try cpuinfo to check your cpu performance.

cpu1 can be activated by your application.
