access to CF card registers doesn't look good

[Holger Schurig]

Hmm, I'm already at the first obstacle.

I insert my CF card ("product info: "Marvell", "802.11 CF", "ID: 
04", "", manfid: 0x02df, 0x8103); my driver loads and I parse 
the CIS. I then get

    mrv8xxx_cs: enter libertas_cs_config() at 134
    mrv8xxx_cs: eth1: at 0.0, irq 11, io 0xc100-0xc17f

The from-to numbers are

   p_dev->io.BasePort1,
   p_dev->io.BasePort1 + p_dev->io.NumPorts1 - 1

Now I map this in and get a dump of the registers:

   mem = ioport_map(p_dev->io.BasePort1, p_dev->io.NumPorts1);
   for (i=0; i<0x200; i+=2) {
         printk("%04x: %04x\n", i, ioread16(card->mem + i));
   }

and I get the dump at the end of my message. However, the spec 
that I have talks in the context of the CF Interface / Firmware 
download:

   Check the Card Configuration and Scratch port register (0x3f)
   - if it is 0x5a, firmware is already there
   - if it is 0x00, bootloader is ready to download firmware
   - else, this register has an invalid value

So the question is: does my card need the helper download?  Am I 
accessing the hardware correctly?  Where am I dumb?
