As per CSU_CSL registers default value ,it has secure read /write permission by default .(CSU_CSL=0x00330033)
I am not getting that even though it has secure read/write access permission then how that peripheral can be accessed from linux kernel.
is it that linux kernel is operating in secure mode?
i want to add CSU for secure and non secure access of peripherals .
so help me on how to enable CSU in imx6.
