/**
* This file is intended to be used to build PSA test driver libraries. It is
* intended to be appended by the test build system to the crypto_config.h file
* of the Mbed TLS library the test library will be linked to. It mirrors the
* PSA_ACCEL_* macros defining the cryptographic operations the test library
* supports.
* This file is intended to be used to build PSA external test driver
* libraries (libtestdriver1).
*
* It is intended to be appended by the test build system to the
* crypto_config.h file of the Mbed TLS library the test library will be
* linked to (see `tests/Makefile` libtestdriver1 target). This is done in
* order to insert it at the right time: after the main configuration
* (PSA_WANT) but before the logic that determines what built-ins to enable
* based on PSA_WANT and MBEDTLS_PSA_ACCEL macros.
*
* It reverses the PSA_ACCEL_* macros defining the cryptographic operations
* that will be accelerated in the main library:
* - When something is accelerated in the main library, we need it supported
* in libtestdriver1, so we disable the accel macro in order to the built-in
* to be enabled.
* - When something is NOT accelerated in the main library, we don't need it
* in libtestdriver1, so we enable its accel macro in order to the built-in
* to be disabled, to keep libtestdriver1 minimal. (We can't adjust the
* PSA_WANT macros as they need to be the same between libtestdriver1 and
* the main library, since they determine the ABI between the two.)
