The firewall framework offers a generic API that is defined in firewall controllers drivers to best fit the specificity of each firewall. There are various types of firewalls: -Peripheral firewalls that filter accesses to peripherals -Memory firewalls that filter accesses to memories or memory regions -Resource firewalls that filter accesses to internal resources such as reset and clock controllers A firewall controller must be probed at arch_initcall level and register to the framework so that consumers can use their services.
