Sam, in case this didn't become clear: the receiving end to which this tool talks resides in firmware deeply embedded within the SoC. It's a function specific to Marvell processors, not u-boot, and activated by talking to the chip before any other software environment is loaded. These chips support booting from a whole variety of peripheral sources to load system images from, both SPI flash and UART are just alternatives. So it's in u-boot as part of the toolchain, not boot firmware.
