How to activate all 4 cores in ls1043ardb using 32 bit compiler

I am using a freescale development board LS1043a-rdb, and the linux-fsl-sdk-v2.0-1701 kernel

 

When I compile linux-fsl-sdk-v2.0-1701 using a 64 bit compiler (aarch64-linux-gnu-) and booted the board. I see all 4 cores activated.

 

But when I compiled linux-fsl-sdk-v2.0-1701 using a 32 bit compiler (arm-linux-gnueabihf-) and booted the board. I only see 1 core activated.

 

How do I activate all the 4 cores when I compile linux-fsl-sdk-v2.0-1701 under 32 bit compiler ?

 

Note in my .config file I have set CONFIG_NR_CPUS=4 (but I still see 1 core activated when i do lscpu or cat /proc/cupinfo).

 

Any help would greatly be appreciated.

 

Thank you.
