As I had mentioned in a review comment in v1, also Bryan had mentioned
his similar concern; this may break our AM6x platforms. While the FIT
seems to have overlapping TIFS stub entries, in reality only one is
selectively loaded. The load addresses are designed with our limited
SRAM in mind so changing it like this may not work.
