0005  * This file is part of the PSA Crypto Driver Model, containing functions for
0006  * driver developers to implement to enable hardware to be called in a
0007  * standardized way by a PSA Cryptographic API implementation. The functions
0008  * comprising the driver model, which driver authors implement, are not
0009  * intended to be called by application developers.
