??? Since the LPCs have no ext buses, only GPIO, you have no choice but
to bit-bang the interface. So it really seems to boil down to how many
GPIOs you want to spend on the interface. If you want to be sure that
you'll be able to support any foreseeable future [compliant] card,
you've really got no choice but to implement a full CF interface.
