Quite reasonable that from the GP TEE Specification POV, the version number associated with a particular binary is nothing directly to do with the source code version number. All that the spec cares about is that BL3 is capable of reporting a single value that increase when changes are made that impact the BL3 binary.

Even the same version of TF-A for different platforms would have different feature set. The other way can be populating a bitmap for various feature during boot time for later use. This way we don't need someone to keep track of features.
yep. And it is quite visible that feature presence should be layered across modules. One thing is generic tf-a features and another one is platform specific. Also through these bits features can be deprecated/removed.
Thanks, Michal
