Yenta Socket work with 32-bit card but not 16-bit

[David Clark]

I have a custom embedded board with a single PCMCIA slot.  The PCMCIA
socket controller is a TI PCI1620 (Yenta).  The processor is a Freescale
MPC8245 (PowerPC 603e core).  I am running Linux kernel 2.6.14.2 and
pcmciautils 014.

The PCMCIA slot works with a 32-bit network card that I have been using
during development.  It does not work with a 16-bit card.  When I plug
the 16-bit card into the socket I get the message "cs: unable to map
card memory"

I have searched many user groups, including this one, and I have played
with various settings in the config.opts file, to no avail.  Admittedly
I don't have a good understanding of how pcmcia works in Linux so
hopefully someone here can direct me.

Below are the outputs for (dmesg, config.opts, iomem and ioports).
Please let me know if any further information would be helpful.  Thank
you for your help.
