[meta-freescale] iMX6Q Linux 3.10.17 Trying to read registers at boot time

Hello

I was derived here from : 
https://community.freescale.com/message/473511#473511

My kernel stops loading when I try to access to registers in 
mach-imx6q.c. I think it has something to do with iMX6 security system. 
Access to that registers at that moment seems to be denied and the 
kernel load crashes.

I am looking for how to change that with no luck.  I found that dts 
configures AIPS registers like this:

aipstz at 0207c000
{

   reg = <0x207c000 0x4000>;

};

but I changed it to:

aipstz at 0207c000

{

   reg = <0x207c000 0x77777777>;

};

and I yet have not access to read that same AIPSTZ1 register from 
mach-imx6q.c

Best regards,
Jose
