[U-Boot] [U-Boot, 07/15] spl: atf: introduce spl_invoke_atf and make bl31_entry private

[Philipp Tomsich]

> 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.
