Merge patch series "ATF and OP-TEE Firewalling for K3 devices."

Manorit Chawdhry <m-chawdhry@ti.com> says:

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.
