This makes it easier to ensure that crypto_spe.h is included everywhere it needs to be, and that it's included early enough to do its job (it must be included before any mention of psa_xxx() functions with external linkage, because it defines macros to rename these functions).

*
|
|
* This file contains platform-dependent type definitions.
|
|
*
|
|
* In implementations with isolation between the application and the
|
|
* cryptography module, implementers should take care to ensure that
|
|
* the definitions that are exposed to applications match what the
|
|
* module implements.
