Hi hackers,

Is trustzone working on exynos 4412 platform?

I have selected the follow item in Fiasco config menu:
 * Platform Timer (Multi-core timer)
 * Use ExtGic
 * Execution Model (TrustZone normal side)

But it stop at early stage.
Same result for Execution Model (Standard mode).
but no message for Execution Model (TrustZone secure side).

If the trustzone is disabled in u-boot, the 'Standard mode' works fine.
