Hi Christopher, Optee Client library has recently been merged to edk2 source code. It tries to provide a generic interface [1] to OP-TEE based trusted applications (pseudo/early).
AFAIK, you don't need any platform specific hook in client interface to work with upstream OP-TEE. So instead you should use Optee library.
