fconf: initial commit Introduce the Firmware CONfiguration Framework (fconf). The fconf is an abstraction layer for platform specific data, allowing a "property" to be queried and a value retrieved without the requesting entity knowing what backing store is being used to hold the data. The default backing store used is C structure. If another backing store has to be used, the platform integrator needs to provide a "populate()" function to fill the corresponding C structure. The "populate()" function must be registered to the fconf framework with the "FCONF_REGISTER_POPULATOR()". This ensures that the function would be called inside the "fconf_populate()" function. A two level macro is used as getter: - the first macro takes 3 parameters and converts it to a function call: FCONF_GET_PROPERTY(a,b,c) -> a__b_getter(c). - the second level defines a__b_getter(c) to the matching C structure, variable, array, function, etc.. Ex: Get a Chain of trust property: 1) FCONF_GET_PROPERY(tbbr, cot, BL2_id) -> tbbr__cot_getter(BL2_id) 2) tbbr__cot_getter(BL2_id) -> cot_desc_ptr[BL2_id] Change-Id: Id394001353ed295bc680c3f543af0cf8da549469 Signed-off-by: Louis Mayencourt <louis.mayencourt@arm.com> 2019-08-08 12:03:26 +01:00			`/*`
