MT6873 bus frabric provides TrustZone security support and data
protection to prevent slaves from being accessed by unexpected
masters.
The security violations are 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 devapc-mt6873 driver. The violation
information is printed in order to find the murderer.
