Hello Chetan,
As Pascal said I had a similar problem and here is how I fixed it -- basically by switching to the latest ARM Foundation model.
2. Extract the archive, say to $HOME. This will create $HOME/Foundation_Platformpkg/.
3. Go to the directory where you did the "repo init ; repo sync" for OP-TEE. This is where you have all the subproject directories (edk2, build and so on).
4. Do: mkdir Foundation_Platformpkg/ ; ln -s $HOME/Foundation_Platformpkg/models Foundation_Platformpkg/models
5. Rebuild and run: cd build ; make -j8 run
This did the trick for me. Please let us know if it works for you.
Regards,
