The DPCM subdriver is a little peculiar, in that it's meant to support devices where LUN 0 is Compact Flash and uses the CB transport whereas LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't really a transport in itself; it's more like a demultiplexer. Much of the DPCM code is part of the SDDR09 subdriver already, and the remaining part is fairly small. This patch (as1182) moves that extra piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is the Kconfig entry for DPCM support; it is now listed as part of the SDDR09 entry. In order to make sure that the semantics are the same as before, each unusual_devs entry for DPCM is now present twice: once with DPCM support if SDDR09 is configured (as before), and once with the SINGLE_LUN flag and CB support otherwise.
