you didnt read enough of the code.  specifically, you missed the fact that 
other config options can compile code in this file even if CONFIG_CMD_PCMCIA 
is disabled.

if you feel like re-architecting and splitting the code to take this into 
consideration, that's one thing.  but it isnt a simple 'move the config option 
into the makefile' fix.
