| 2 | These are brief instructions on how to add support for CF adapters to |
| 3 | custom designed PXA boards. You need to set the parameters in the |
| 4 | config file. This should work for most implementations especially if you |
| 5 | follow the connections of the standard lubbock. Anyway just the block |
| 6 | marked memory configuration should be touched since the other parameters |
| 7 | are imposed by the PXA architecture. |

| 46 | Another important point is that maybe you have to power the pcmcia |
| 47 | subsystem. This is very board specific, for an example on how to |
| 48 | do it please search for CONFIG_EXADRON1 in cmd_pcmcia.c |
