sh7785: enable_mmu crashes

[Altunbas Sabri (DC-IA/EAH2)]

Hi,

I port linux-3.12.1 on my board with sh7785lcr. It crashes at the following point.
 
Can anybody give me please some hints. 

The crash is at that point where mmu is initialised

void __init setup_arch(char **cmdline_p)
{
	enable_mmu();
..
..
}


Befor step
