The CNTACRn register controls secure vs. non-secure access for particular registers in a frame regardless of which view is used. The CNTPL0ACRn is not a security restricted register and it can only restrict access to certain registers in the second view. No combination of settings in these registers can restrict access to only the second view in a frame with two views. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
