K3 devices have firewalls that are used to prevent illegal accesses to memory regions that are deemed secure. The series prevents the illegal accesses to ATF and OP-TEE regions that are present in different K3 devices.
AM62X, AM62AX and AM64X are currently in hold due to some firewall configurations that our System Controller (TIFS) needs to handle. The devices that are not configured with the firewalling nodes will not be affected and can continue to work fine until the firewall nodes are added so will be a non-blocking merge.
