Split crypto_driver.h into 4: * crypto_driver_common.h for common definitions, not meant to be included directly by driver code. * crypto_accel_driver.h for drivers that work with transparent key material. * crypto_se_driver.h for drivers that work with opaque key material. * crypto_entropy_driver.h for drivers of entropy sources. There is no code change in this commit, I only moved some code around.

/**

* \file psa/crypto_driver_common.h
|
|
* \brief Definitions for all PSA crypto drivers
|
|
*
|
|
* This file contains common definitions shared by all PSA crypto drivers.
|
|
* Do not include it directly: instead, include the header file(s) for
|
|
* the type(s) of driver that you are implementing. For example, if
|
|
* you are writing a driver for a chip that provides both a hardware
|
|
* random generator and an accelerator for some cryptographic algorithms,
|
|
* include `psa/crypto_entropy_driver.h` and `psa/crypto_accel_driver.h`.
|
|
*
|
|
* This file is part of the PSA Crypto Driver Model, containing functions for
|
|
* driver developers to implement to enable hardware to be called in a
|
|
* standardized way by a PSA Cryptographic API implementation. The functions
|
|
* comprising the driver model, which driver authors implement, are not
|
|
* intended to be called by application developers.
