Tegra194: memctrl: force viw and vifalr/w transactions as non-coherent
Krishna Reddy authored 
Force memory transactions from viw and viflar/w as non-coherent from
no-override. This is necessary as iso clients shouldn't use coherent
path and stage-2 smmu mappings won't mark transactions as non-coherent.
For native case, no-override works. But, not for virtualization case.

Trusted Firmware-A

Trusted Firmware-A (TF-A) is a reference implementation of secure world software for Arm A-Profile architectures (Armv8-A and Armv7-A), including an Exception Level 3 (EL3) Secure Monitor. It provides a suitable starting point for productization of secure world boot and runtime firmware, in either the AArch32 or AArch64 execution states.

TF-A implements Arm interface standards, including:

The code is designed to be portable and reusable across hardware platforms and software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A with reference implementations of Arm standards to benefit developers working with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration testing, on any secure world code derived from TF-A.
