(I'm not sure if U-Boot uses SPI for anything else anyway...)
it can be useful for booting an FPGA. On some architectures this is faster than GPIO bit bang. This is of course board dependent, as implementation of the actual FPGA functions is in the board code anyways. (Using this in a not-yet-published board.)
Another use could be SPI-controlled displays (framebuffer driver for displaying a boot loge etc.). Did not have time to implement this yet, unfortunately... ;-)
Best regards, Wolfgang
