Storage Abstraction Layer¶

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

Each platform should register devices and their drivers via the storage layer. These drivers then need to be initialized using the tftf_platform_setup() function.

Warning

It is mandatory to implement at least one storage driver.

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/.
