As you commented, I got the board that firmware was preloaded.
Unfortunately, I didn't know the any routine to contact firmware developer
and developer about SoC design.
Dear Kukjin,
I need your help about CPU0 issue of Exynos SoC.
Could you answer why CPU0 cannot be hotplugged on Exynos SoC?
Thanks,
