You need to make more iomem and ioport resources available. Especially some
which are _not_ used as Memory windows or I/O windows on the socket by
default. E.g. on my notebook's yenta sockets there is

Memory window 0: 30400000-307ff000 (prefetchable)
Memory window 1: 30800000-30bff000
I/O window 0: 00004000-000040ff
I/O window 1: 00004400-000044ff

but my /etc/pcmcia/config.opts does not even contain these resources:

include port 0x100-0x4ff, port 0x800-0x8ff, port 0xc00-0xcff
include memory 0xc0000-0xfffff
include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff

Hi,
Thanks Dominik.
Well, I added some iomem and ioport resources in my config.opts file with no
change, I still have the same message :

With these windows in my config.opts file :
include port 0x00000000-0x00000fff, port 0x00001000-0x00001fff
include port 0x00002000-0x00002fff, port 0x00003000-0x00003fff
include port 0x4000-0x40ff, port 0x8000-0x8fff
include memory 0xc0000000-0xc0ffffff, memory 0xc4000000-0xc4ffffff
include memory 0xc2000000-0xc3ffffff, memory 0xc6000000-0xc7ffffff
include memory 0xa8000000-0xa9ffffff, memory 0xae000000-0xaeffffff


The error comes from find_mem_region in drivers/pcmcia/cistpl.c :
  if (!(s->features & SS_CAP_STATIC_MAP) && mem->res == NULL) {
	mem->res = find_mem_region(0, s->map_size, s->map_size, 0,
				   "card services", s);
	if (mem->res == NULL) {
	    printk(KERN_NOTICE "cs: unable to map card memory 0x%x!\n",
s->map_size);
	    return NULL;
	}

Nevertheless, my PCI configuration seems ok :
- From my MIPS processor, the PCI mem space is mapped to 0xc0000000 that is
mapped to the PCI physical address 0xc0000000.
- The PCI IO space is mapped to 0xe0000000 that is remapped to the PCI
physical address 0x00000000.

An idea ? Thanks a lot for your help.
