Re: [oc] PC-CARD/PCMCIA controller core

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

Hi Richard,

I know about that. Currently we are only using ATA cards and want to add support for
"real" PC-cards. What I am not sure about is how ATA cards are handled by PC-card controllers.
Are they used in ATA mode or are they used different ?
