Secure SPI-NOR Provisioning

The SPI-NOR flash is an external secure NOR flash that is used by the Trusted Execution Environment on the Tegra device for persistent storage of cryptographic assets. The SPI-NOR flash supports authenticated memory access which rely on a shared symmetric secret known by both the Trusted Execution Environment and the SPI-NOR flash. FSKP programs this shared secret and device security settings into the flash.

One time SPI-NOR provisioning occurs automatically during the next boot after the board's FUSE_SECURITY_MODE is burnt..
