I have a board here which roughly resembles a DB1100, AFAICT. My problem is
that I can't get the CompactFlash card to be recognized, and I don't even
know where exactly it fails.
So, a few questions up front:
1. CompactFlash is accessed via PCMCIA, it does not use the MTD
infrastructure, right? I also read that the CF then appears as a normal(?)
ATA device. So, what should be the right drivers for it?
2. How can I find out if it's looking at the right addresses? I just need some
kind of register which I can probe to find out if the device is where I think
it should be.
Hmm, in fact I'd be happy about _any_ hint the would get me further. I'm
Appended is a patch that removes an unused variable, something I found while
trying to understand what's going on there.
