This works by starting up U-Boot VPL, which gets to SPL and then sets up a
UPL handoff using the FIT containing U-Boot proper. It then jumps to U-Boot
proper and runs a test to check that the parameters are correct.
The entire FIT is loaded into memory in SPL (in upl_load_from_image()) so
that it can be inspected in upl_test_info_norun
