Good questions, it does seem quite excessive. Interestingly enough,
there is a platform option for the IDE driver as well
(CONFIG_BLK_DEV_PLATFORM): could it be the a better way to drive the
CF card in true IDE mode?

I must be missing something very basic, but can't get over this hurdle:

if I enable PATA platofrm, and define the card local bus/card in the
dts file, the card gets detected and properly recognized, but no
device seems to be created in /dev, so the card does not get mounted
when the board comes up.


If I enable CONFIG_BLK_DEV_PLATFORM instead (and no dts file
definitions), I can't get the probe function to be invoked, so the
card does not even get detected.

People, does anyone have CF card up and running in 2.6.25 - please,
share your secrets! :-)

Seriously, it is quite frustrating, I would really appreciate any extra hints,

TIA,
vadim
