Yes, that's true, there are dependencies. When not satisfying these,
one can face build or runtime failures.
As for now, it is recommended to always synchronize package/optee-*
packages with boot/optee-os package.

Using an older OP-TEE revision with BR currently needs one to use
external packages, whatever way (i.e. src_override).
I cannot tell whether BR should natively provide support for previous versions.

That said, yes, I think it would be fine some older versions are still
supported.

I can give it a try for few older version numbers.

Etienne
