There are two types of firewall: region based firewall and channelized firewall.
The channelized firewall is only implemented to protect the registers which control the power domain and LPSC for security enclave. User can’t modify the channelized firewall setting.
Region based firewalls are inserted at the target end point in the interconnect. Normally a group of the target interfaces share one region-based firewall. Each region-based firewall has its unique configuration of:
Majority of the memory regions in the SoC are protected by region-based firewalls, except the public boot ROM, debug cell, and STM.
Table 3-6 shows provides the firewall summary on SoC.
