4In order to improve platform independence and portability a storage abstraction
5layer is used to store test results to non-volatile platform storage.

Jimmy Brisson06b5be42020-04-02 15:19:27 -05007Each platform should register devices and their drivers via the storage layer.
8These drivers then need to be initialized using the ``tftf_platform_setup()``
9function.

Jimmy Brisson06b5be42020-04-02 15:19:27 -050011.. warning::
12 It is mandatory to implement at least one storage driver.
13
14For the FVP and Juno platforms the NOR Flash driver is provided as the default
15means to store test results to storage. The storage layer is described in the
16header file ``include/lib/io_storage.h``. The implementation of the common
17library is in ``drivers/io/io_storage.c`` and the driver files are located in
18``drivers/io/``.
