To perform the operation, the request goes to the RSA HW engine. Once the operation is done, the response is sent back via firmware and ATF to the linux driver. Meanwhile the API in the linux driver waits until the operation is complete. This is why the driver is synchronous and therefore the CRYPTO_ALG_ASYNC flag is not set.
But you use crypto_engine, right? That is always async regardless of what your driver does.
