I guess, that you have noticed that pccard is doing this kind of stuff today,
and isn't doing it particular well, since nobody knows what to do :-(
It seems to me that we have several kinds of devices:
1. things which say: give me 0x200-0x21f, (similar for iomem, irq & dma).
2. things which say: give me one of {0x200-0x21f,0x300-0x31f,0x320-0x33f}
(similar for iomem, irq & dma).
3. things which say: give me 0x20 ioaddresses. (similar for iomem, irq & dma)
Now, we need to cater for all of these one way or another, and it doesn't
get any easier when some pieces of HW use method 2 for port, 1 for irq and
3 for iomem.
Anybody thought about this from scratch ?
