For the FVP and Juno +platforms the NOR Flash driver is provided as the default means to store test +results to storage. The storage layer is described in the header file +``include/lib/io_storage.h``. The implementation of the common library is in +``drivers/io/io_storage.c`` and the driver files are located in ``drivers/io/``. + +-------------- + +*Copyright (c) 2019, Arm Limited.
