+
+Flashing images to eMMC:
+
+The following commands can be used to download tiboot3.bin, tispl.bin,
+u-boot.img, and sysfw.itb from an SD card and write them to the eMMC boot0
+partition at respective addresses.
+

+=> fatload mmc 1 ${loadaddr} sysfw.itb
+=> mmc write ${loadaddr} 0x3600 0x800
+
+To give the ROM access to the boot partition, the following commands must be
+used for the first time:
+=> mmc partconf 0 1 1 1
+=> mmc bootbus 0 1 0 0
+
+To create a software partition for the rootfs, the following command can be
+used:
