By default bootmenu is loaded only from eMMC. After this change U-Boot first tries to load bootmenu from uSD card and if it fails then fallback to eMMC. People want to boot alternative OS from removable uSD without need to modify eMMC content. So this backward compatible change allows it. Part of this change is also optimization of trymmc* macros so they can be used in preboot macro for loading bootmenu.
