This adds a new interface spl_invoke_atf() that takes a spl_image_info argument and then derives the necessary parameters for the ATF entry. Based on the additional information recorded (into /fit-images) from the FIT loadables, we can now easily locate the next boot stage.
We now pass a pointer to a FDT as the platform-specific parameter pointer to ATF (so we don't run into the future headache of every board/platform defining their own proprietary tag-structure), as FDT access is already available in ATF.
With the necessary infrastructure in place, we can now update the support for the ARM Trusted Firmware to dispatch into the spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is loaded.
