imx53 trustzone: enabling MMU in normal world problem?

I have tested running linux kernel in secure world. But when i load kernel in normal world, it hangs when flipping last bit of control register(enable MMU). I doubt maybe it is caused by some hardware initialization code which blocks MMU access from normal world. Anyone facing this problem?
