| 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. |

| #define CONFIG_PCMCIA_SLOT_A 1 |
| /* just to keep build system happy */ |

| #define CFG_IDE_MAXBUS 1 |
| /* max. 1 IDE bus */ |
| #define CFG_IDE_MAXDEVICE 1 |
| /* max. 1 drive per IDE bus */ |

| #define CFG_ATA_IDE0_OFFSET 0x0000 |

| /* Offset for data I/O */ |
| #define CFG_ATA_DATA_OFFSET 0x1f0 |
| |
| /* Offset for normal register accesses */ |
| #define CFG_ATA_REG_OFFSET 0x1f0 |
| |
| /* Offset for alternate registers */ |
| #define CFG_ATA_ALT_OFFSET 0x3f0 |

| |
| 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 |
