Several files among include/psa/crypto_*.h are not meant to be included directly, and are not guaranteed to be valid if included directly. This makes it harder to perform some static analyses. So make these files more self-contained so that at least, if included on their own, there is no missing macro or type definition (excluding the deliberate use of forward declarations of structs and unions).

/**
|
|
* \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 dynamically registered driver for a secure element,
|
|
* include `psa/crypto_se_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.
