now the semi-obvious question ... how does this differ from the old spi_mmc.c 
driver ?  i see this doesnt rely on the legacy mmc framework, but what about 
device/commandset support parity ?

it's too bad the new framework doesnt allow for dynamic probing like the spi 
layer.  makes it a pain to work with a SPI/MMC card that can have the CS 
changed on the fly.
