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.

|

|
||||
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
