The partitions variable is especially useful to create a partition table from U-Boot, either directly from the U-Boot shell, or through flashing tools like fastboot and its oem format command. This is especially useful on devices with an eMMC you can't take out to flash from another system, and booting a Linux system first to flash our system then is not really practical.
