Hi,

Happy new year!

For NVIDIA Tegra platforms, we need the capability to query the BL31 version (e.g. 2.7, 2.8, 2.8.x) from the NWd at runtime. I could not find an FID that returns this value.

I propose we introduce a new runtime service in bl31 that returns the version_string to the NWd to support this requirement.

Thoughts?
