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
