- 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.
- EDIT 2010-07-01: in common/cmd_ide.c, having CONFIG_PXA_PCMCIA defined
- would cause looping on inw()/outw() rather than using insw()/outsw(),
- thus making sure IDE / ATA bytes are properly swapped. This behaviour
- is now controlled by CONFIG_IDE_SWAP_IO, therefore PXA boards with
- PCMCIA should #define CONFIG_IDE_SWAP_IO.
- #define CONFIG_IDE_SWAP_IO
- #define CONFIG_PXA_PCMCIA 1
- #define CONFIG_PXA_IDE 1
- #define CONFIG_PCMCIA_SLOT_A 1
- /* just to keep build system happy */
- #define CONFIG_SYS_PCMCIA_MEM_ADDR 0x28000000
- #define CONFIG_SYS_PCMCIA_MEM_SIZE 0x10000000
- #define CONFIG_SYS_MECR_VAL 0x00000000
- #define CONFIG_SYS_MCMEM0_VAL 0x00004204
- #define CONFIG_SYS_MCMEM1_VAL 0x00000000
- #define CONFIG_SYS_MCATT0_VAL 0x00010504
- #define CONFIG_SYS_MCATT1_VAL 0x00000000
- #define CONFIG_SYS_MCIO0_VAL 0x00008407
- #define CONFIG_SYS_MCIO1_VAL 0x00000000
- /* memory configuration */
- #define CONFIG_SYS_IDE_MAXBUS 1
- /* max. 1 IDE bus */
- #define CONFIG_SYS_IDE_MAXDEVICE 1
- /* max. 1 drive per IDE bus */
- #define CONFIG_SYS_ATA_IDE0_OFFSET 0x0000
- #define CONFIG_SYS_ATA_BASE_ADDR 0x20000000
- /* Offset for data I/O */
- #define CONFIG_SYS_ATA_DATA_OFFSET 0x1f0
- /* Offset for normal register accesses */
- #define CONFIG_SYS_ATA_REG_OFFSET 0x1f0
- /* Offset for alternate registers */
- #define CONFIG_SYS_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
