This is to support SPL for i.MX8QXP MEK board and default support SPL. In this patchset, use SPL FIT, but actually we could not use SPL FIT for secure boot, in NXP vendor tree, there is another format called container, NXP use SPL + container for secure boot. The container support is on my TODO list. But to make SPL work in upstream, use SPL FIT here.
