/* 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. */
