Passing the index of booting MMC interface from SPL to u-boot.bin

On beaglebone black, which are based on TI AM3358, the booting of U-Boot is split into two phrases, MLO and u-boot.bin/img. There should be a way to pass the index of the booting MMC interface from MLO to u-boot, so that the uboot.env in the FAT file system on the booting card could be read from
