tiny-printf variant doesn't know how to handle %llu format string, but both tiny-printf and print_size can meet in SPL when TFTP is used to obtain main u-boot image. This is known to lead to critical boot issue at AM335x platform when printf is catched in infinite loop.
To avoid such issues and make print_size function tiny-printf friendly, use %u instead of %luu. Note, that the size value is guaranteed to be less than 1024 in this conditional branch, so the cast to unsigned int is safe.
