+These are brief instructions on how to add support for CF adapters to 
+custom designed  PXA boards. You need to set the parameters in the 
+config file. This should work for most implementations especially if you
+follow the connections of the standard lubbock. Anyway just the block
+marked memory configuration should be touched since the other parameters 
+are imposed by the PXA architecture.

+Another important point is that maybe you have to power the pcmcia 
+subsystem. This is very board specific, for an example on how to
+do it please search for CONFIG_EXADRON1 in cmd_pcmcia.c
