I can't see much reason to add support for U-Boot acting as a SPI slave, 
and these patches certainly doesn't attempt to make that happen. If 
you're thinking of the new "struct spi_slave", that's a reference to the 
SPI slave we're talking to, i.e. whatever sits at the other end of the 
SPI bus.

If someone else wants support for slave-mode SPI, maybe we should add 
it, but that should be an entirely separate set of patches.
