More specifically, U-Boot is configured to check if there's a uSD card present and boots from it if found. This is intended as a convenience and the details are specific to the version of U-Boot you have installed. If you want to change this behavior, you can modify the U-Boot startup script or (in some cases) remove the boot files from your uSD card.
