The ums command (presenting a U-Boot block device as a USB mass storage device) is very useful for accessing eMMC devices via USB-OTG.
At the moment we enable USB fastboot by default for Allwinner devices, so it makes sense to do the same with USB mass storage, which is actually more versatile and can be accessed on any USB host easily.

UMS or any secondary-emmc accessible are considered in production u-boot config instead of mainline u-boot since we have fastboot already available for this kind of purpose. This might be one of the reason not conisidered UMS by default till now, atleast on Allwinner.
Thanks, Jagan.
