MediaTek bus fabric provides TrustZone security support and data protection to prevent slaves from being accessed by unexpected masters. The security violation is logged and sent to the processor for further analysis or countermeasures. Any occurrence of security violation would raise an interrupt, and it will be handled by mtk-devapc driver. The violation information is printed in order to find the murderer.
