Actually earlier platforms did not had this support,  support for either RNDIS boot mode (CONFIG_SPL_USBETH_SUPPORT) or
CONFIG_SPL_USB_SUPPORT (boot from mass-storage device) were only supported.

But ideally, this should work on any other platform, as functional flow of SPL-DFU is same as DFU functionality in u-boot and
reuse of common dfu driver, also DFU has been verified in multiple platforms in u-boot mainline.
The same DFU support is now brought to SPL to facilitate booting EVM using USB interface.
