/* TODO: The error code allocation needs to be revisited:
*
* - Should we make (some of) the MPS Reader error codes public?
* If so, we need to adjust MBEDTLS_MPS_READER_MAKE_ERROR() to hit
* a gap in the Mbed TLS public error space.
* If not, we have to make sure we don't forward those errors
* at the level of the public API -- no risk at the moment as
* long as MPS is an experimental component not accessible from
* public API.
