Configuring the Security Configuration Registers

Tegra has separate registers for configuring bridge client security, bridge firewalls, known as security configuration registers (SCRs). SCRs are either configured by the platform or re-configured for custom platforms. Custom configuration is are provided using MB1 BCT at the MB1 stage.

The list of SCRs for re-configuration for custom platforms is the same in MB1 device-side code and SCR platform data. SCR register addresses hard coded in MB1 can contain data from the platform. The data cannot be masked, and is written to the registers as is.

The SRC configuration file is available at:
