Secure Memory Touch Arbiter is the same thing as the TrustZone Protection Controller found on A31/A31s. Access to many peripherals on the H3 can be controlled by the SMTA, and the settings default to secure access only. This patch supports the new settings, and sets them to allow non-secure access.
