/* The #MBEDTLS_PSA_INJECT_ENTROPY feature requires two extra platform
 * functions, which must be configured as #MBEDTLS_PLATFORM_NV_SEED_READ_MACRO
 * and #MBEDTLS_PLATFORM_NV_SEED_WRITE_MACRO. The job of these functions
 * is to read and write from the entropy seed file, which is located
 * in the PSA ITS file whose uid is #PSA_CRYPTO_ITS_RANDOM_SEED_UID.
 * (These could have been provided as library functions, but for historical
 * reasons, they weren't, and so each integrator has to provide a copy
 * of these functions.)
 *
 * Provide implementations of these functions for testing. */
