[Ltib] Compact Flash on MPC8349ITX?

Hello LTIB Gurus!

I'm trying to get the Compact Flash interface on the MPC8349ITX board to work.
I have downloaded from the Freescale website the LTIB MPC8349ITX dated
20070212 and programmed u-boot and that works fine. I can get u-boot
to display the partition table of the Compact Flash card I inserted (ide part), and can read sectors (ide read) from it into RAM. It also prints a nice message when
booting telling me the serial number, manufacturer name and size
of the CF card. So I think u-boot is working fine.

I have also built a linux kernel and booted it by TFTP/NFS without difficulty. I am not trying to boot directly from the compact flash card yet. That is a step that I will tackle later. All I want at this stage is to be able to access files
on the compact flash drive by mounting the device into an already
running Linux system.

But now that the kernel is booted, I don't know how to access the CF card
(as /dev/hda[1-4]?). The kernel is the same as in the BSP mentioned
above (2.6.13). Nothing is printed about the compact flash during the kernel's
boot process. I found some kernel options related to PCMCIA, but don't
think that's what I want to try. (I tried them anyway out of desperation
but they didn't help).

I suspect that either I need to enable one or more options in building
the kernel and/or enable one or more packages while building LTIB.
I would appreciate any help anyone can provide to point me in the
right direction.

Thanks in Advance!
